My Acer Aspire 4330 Series was working just fine yesterday at the library (where I have to go to get on WiFi). When I took it home and plugged it in, suddenly the entire right-hand half of the screen was--not grayed out exactly, but...the best word I can think of is "foggy." I can still see what's on that part of the screen, but it's...foggy. It's as if there was a gray filter fitted over half the screen. The cursor arrow casts a little shadow when it goes into that part of the screen, and the words in this post that are there are...darker and thicker-looking. (This doesn't seem to be true of my own word-processing files. It does, however, affect the color of websites I visit and of my solitaire game.) This malady occurred about an hour after the previous use of the laptop. It is occurring now, even though I'm at the library again. This leads me to think that the problem is unconnected to the power source. I tried shutting down and rebooting; no change. What's going on, and what can I do about it?
