Hello reader, I'm partially sighted, and at the moment i'm using a Mac. I like the magnifier on the Mac; it zooms-in on where the cursor is pointed and the entire screen is enlarged. My Mac is on its last legs, and i will be moving to a P.C. A friend has a P.C., and i find the built in magnifier weak and it only zooms in on half of the screen. Can i buy quality magnifier software? Can you recommend anything? Michael.
