<div dir="ltr"><div class="gmail_quote">Hello Phillip,<br><br>Here at IU, we have network versions of JAWS Professional Version 9.0.2169 and ZoomText Version 9.14 (Level 2) running on the Vista build in our student computing labs. <br>
<br>We don't have any problems with running them both at the same time on Vista (we are using Vista Enterprise). We've played around with running JAWS, ZoomText, and Kurzweil 3000 in all possible combinations and in general never experienced any crashes or significant problems other than the general confusion of having two or more programs talking to you at once. The one exception is when both JAWS and ZoomText are running at the
same time (starting order doesn't matter), and then JAWS is closed it does causes Vista to crash / generate a blank blue
screen. Running both JAWS and ZoomText works fine, though, as long as ZoomText is closed before closing JAWS. We don't see it as much of an issue as few of our users use both products at once. If JAWS crashes, it has not been seen to take ZoomText or the system down with it.<br>
<br>We experimented briefly with MAGic, due to some difficulties we were having initially getting ZoomText's unsigned mirror driver to install as a fully automatic (non-interactive) silent install (it installs fine if installed manually). If an attempt is made to run both MAGic and ZoomText at the same time (silly I know), a blue screen of death with instantly occur. We didn't have any problems with having JAWS, MAGic, and ZoomText all installed at once as long as ZoomText and MAGic were not launched at the same time. In our testing, we noticed that both MAGic and ZoomText would occasionally seem to freeze up briefly (for 1-5 seconds) when panning the screen on machines that had only 1GB of RAM in them. Both appear to work fine on worstations that have 2GB of RAM installed on them. <br>
<br>A downside of Vista, is that both ZoomText and MAGic had trouble performing text smoothing on text chararcters that appear in certain parts of the start menu and other program menus that Vista presents even if the font smoothing display setting is turned off. Another downside seems to be that in Vista, both MAGic and ZoomText seem to do a less than stelallar job of tracking the input focus and panning the screen accordingly. Even when exiting either ZoomText or MAGic they would frequently not pan the display over to their "Do you really want to close..." dialog boxes. This can make it rather confusing to new and sometimes experienced users alike!<br>
<br>After we figured out how to sign ZoomText's mirrored display driver with one of our own software publishing/signing certificates as sort of outlined in the Microsoft document "Step-By-Step Guide to Device Driver Signing and Staging", we were able to get it to install automatically and didn't pursue using MAGic as our low vision clients prefer ZoomText.<br>
<br>The JAWS silent installer somehow manages to get its mirrored display driver to install on Vista even though it is marked as unsigned, but the Freedom Scientific Braille display drivers fail to install as they also are unsigned. We have not yet persued signing their Braille display drivers. NOTE: This is NOT a problem if you are manually installng JAWS. The lack of Braille display drivers only occurs on unattended slient installs that run in a non-interactive mode (scheduled tasks, deployed through group policy, etc.).<br>
<br>The mirrored display drivers seem more stable than their driver chaining ancestors. We were able to both install and uninstall in any order any of JAWS, MAGic, and ZoomText without having any effect on the functionality of the others or the stablilty of the system. Also, we could upgrade/downgrade the video display drivers without needing reinstall or run the mirror display applications as admin -- this is a great advance as it makes maintaining the machines much much easier! <br>
<br>Unlike the display driver chaining model, mirrored display drivers sit in parallel with the display driver that is running the physical graphics card / display. The Graphics Device Interface layer of the Vista OS sends parallel copies of drawing operations to the physical display drivers as well as any mirrored display drivers that are operating. This allows screen reading applications to use or ignore those drawing operations as they see fit inorder to develop their own model of the information being presented on the screen. Since they all operate in parallel, a mirrored display driver can not affect what appears on the real display or any of the other mirrored display drivers. On some XP builds, we would get random blue screens / crashes on machines that had ZoomText installed (even when it wasn't operational) despite working with AI Squared's technical support folks we could never get a fix for that, so ZoomText was taken off of those machines. Hopefully, the mirrored display drivers will continue to prove to be more stable as our experience so far has convinced the teams responsible for the builds to all the programs to be installed everywhere once again.<br>

I have heard that there is a problem running both Zoomtext and Jaws in<br>
Vista. Anyone know about this? I think it had something to do with<br>
video chaining -- can anyone explain that, and provide info based on<br>
their experience?<br>

Hi Phillip,<br>
<br>
We have ZoomText 9.1 and Jaws 9.0 installed on Windows Vista Business.<br>
That image is deployed across 55 computers throughout our office. In my<br>
experience, the two programs can coexist just fine on the same machine,<br>
so long as you don't try to run them simultaneously. If you want to see<br>
a rather spectacular system crash: launch ZoomText, launch Jaws, and<br>
then exit Jaws.<br>
<br>
Vista no longer utilizes video chaining as it was implemented in XP.<br>
Now, there's the "Mirror driver", which many screen readers utilize in<br>
order to access information being displayed. However, the Mirror driver<br>
apparently doesn't support magnification, so ZoomText is undoubtedly<br>
using an alternate API I'm not familiar with.<br>
<br>
In short though, if you just want the two programs to be installed on<br>
the same machine, you're fine; but, if you were hoping to run them<br>
simultaneously, you might want to consider another solution such as<br>
MAGic.<br>
