Thank you to everyone!
Decided to stick with IE, at least for now, since that's the only browser I've ever used and it's so familiar.
I did go back and re-download IE 7 after uninstalling it, and everything is still okay with internet options, so looks like I got a clean install this time.
However, there's yet another mystery on this pc - something that began a couple weeks ago, out of the blue, and I have no idea what started it. Switching back to IE 6 did not clear it up, so I don't think it's related to that other deal.
When I click to open a webpage from my desktop, the window that opens is tiny... about 8" wide by 1 1/4" high.
When it first began, I hadn't changed any options or settings to cause this... it just suddenly started doin it. I have run Spybot Search and Destroy along with my anti-virus program and all is well there...
Any thoughts, please?
Thanks!
