I was dabbling in the magnifier program (programs>accessories>accessability) and I hit the high contrast option which changed my computer into a black bacground, white texted, 48 pt. beast. My icons are at least a full square inch a piece. I've tried to change the settings back manually by (right-click>properties>appearance>windows standard) but it locks up every time I hit "ok" or "apply." I've tried changing the setting individually, but that doesn't work either (locks up). I've tried changing the setting in magnifier, but it says high contrast is off. I turn it on, then back off again, and nothing changes. Any suggestions?
