I've read several posts about problems relating to the Vista magnifier.
Just a suggestion. The Free ZOOMIT magnifier works great with
Vista and is much easier to use. When you want to use Zoomit it
enlarges the entire visual area of your monitor and allows you to
use the mouse to move things around so you can view them better.
Just a simple right click or hitting escape turns it on. There is a key
command (you can use default or establish your own) that turns
it on.
