This has been superseded by a new release:
I've just posted a quick test of Virtual Magnifying Glass Portable for folks to try out. It's a magnifying glass utility that lets you zoom in on ares of the screen in Windows. It's handy for folks with visual impairments as well as designers. I'd done a quick package of this a while back on the request of someone teaching a class with visually impaired students. This will be a move to making it an official released and supported app as well as the debut app of the new Accessibility category here at PortableApps.com. Please give it a quick try and post back, thanks!
