Lately I've been having a really annoying problem. About every 2-3 days randomly both of my internet viewers (IE and AOL) suddenly switch to the largest fonts on their own. AOL is a real pain because I have to reset the computer for the changes to take affect after I fix it. Anyone know what could cause this? I've run all sorts of spyware and virus checking but nothing pops up. I'm using Windows XP Home.
