What's wrong with the magnifier built into Windows that you're looking for another tool?
Maybe for another OS (Linux, Mac OS). Maybe different requirements? You didn't tell.
Hey guys,
I'm looking for a tool that places a small box near your mouse and everywhere you go - you get a "Zoom" showen. Not just images/videos... everything.
Waiting for your help,
thanks!
