So here I am using FIREFART to go on the internet and find out what to do! Damn! Good thing I've got the sucker on the same machine (I'm not "anti-Firefox", i just don't use it that much except to check my page renderings).
The fix (at least for me):
1) Go into Control Panel, and choose "Internet Options".
2) Under the "Advanced" tab, press the "RESET" button at the lower right:
Don't ask me why this happens, or why the fix works. That's a BUG, D00D - I don't care how you slice it!
