Hi Reeva,
It is my understanding that Window-Eyes can read what is under the mouse 
pointer using two different techniques. The first, which has been around a very 
long time, is the off screen model (OSM). The OSM is a database that stores 
where stuff is on the screen. Or at least where the screen reader thinks stuff 
is on the screen. The OSM is populated by hooking into the video and 
interpreting the data that the CPU sends to the graphics card. The problem with 
this technique is that it is basically hacking the operating system. And, as 
time goes on, it will be harder and harder for screen readers to maintain an 
accurate OSM due to security restrictions in the operating system. Because of 
this and other complexities, the OSM is not always accurate and can't be relied 
upon in all programs and areas of Windows. The second is by using User 
Interface Automation (UIA). This is a more modern and secure approach that 
allows a screen reader to query the application directly to ask it where th
 ings are. For example, UIA is available in Internet Explorer and might be what 
Window-Eyes uses for mouse reading. I hope this bit of background helps you 
better understand why there are limitations and inconsistencies in reading what 
is under the mouse pointer.
Best,
Marc

Subject: Mouse keys?

Ok, have a question. I've been trying to not use the physical mouse as much
since at ginormous magnification it's more time consuming. I'm using zt
fusion with we key layout but ran into this when i was using zt and we
together as seperate products. When i try using the mouse keys, most of the
time it just dings at me. Um, what am i doing wrong?
