Hey all, I'm new to the forums, but an adept apple user as I'm a graphic designer. I recently purchased a new imac running leopard. I'd been using it for a couple of days with no problems, and today I finally got around to installing a bunch of programsCS3, Office 04, Symantec Anti Virus (required for my job). I also run vonage if that matters. Anyway, I was doing some sensitive stuff on an encrypted webpage, and right after I was finished, I logged back in to the page to check the status of what I had done, and the whole screen switched to a striped blue screen. I tried clicking, hitting enter, etc., but nothing happened so I force shut down the computer and restarted. So maybe it's just me being new to leopard, but what the heck (read: $&*%$!) happened? I've never had such a thing happen on any other Mac OS. It freaked me out considering that I had just been doing some sensitive stuff online. But I think I am a pretty secure user. No bittorrent, no pirated programs, no downloading spam attachments, or going to porn sites . I don't use the admin account as my primary user, I use the built-in firewall, none of my passwords are easy, etc., etc. Thoughts? Thanks so much in advance!
