Hi,
The Windows UpDater just downloaded and installed the latest Microsoft updates. I included the Nvidia update also. That was a big problem!
I strongly suggest that you CLOSE ZoomText before allowing this graphics update!!!
The graphics update forced Zoom Text to CLOSE down. But it seems not to have been compleated. After several flashes & repaints of the screen, the mouse moved OK but would not activate anything.

I had to use the keyboard to go to the START Menu, but could not reboot or CLOSE any programs. SpyBot Search & Destroy (anti malware) poped-up several times to ask me about allowing changes to the Window Registry. I think I got them in OK.?.?.
After waiting and clicking and typing with no results for 1/2 hour, I only could use CNTRL_ALT_ DEL twice.

I got it to shut down. Then I got Windows VISTA eventually to came back up OK.
