Ok. Here's the problem: alot of times when I go to type in a name of someone like to PM them, instead of the drop down for the names, the whole message window goes white. Is it just my pc or what?

What version of IE are you using? I know people using IE7 have had that issue before. You will need to upgrade the version to 8 at least and it should work.

Or even better: Firefox!

It does it on IE 7 and firefox

Could be a problem with your Java, which I think the autocomplete uses, or a security setting in both browsers.

It does it on IE7 only. Please upgrade to IE8 or use an alternate browser (e.g. chrome or firefox).

I had a simillar problem when I was useing IE7. On mine my whole screen went a random colour randomlly when typeing things while IE7 was running. It stoped when I upgraded to IE8, I don't trust Firefox.

Don't tru- What??? Why would you not trust firefox? You do realise that it actually is more well programed than IE right!?

I know several people who work with HTML, who say IE makes their lives miserable cause it doesn't handle HTML properly or somesuch.

I know a professional web programmer, he also says he hates IE. Not only does it make you significantly more likely to get a virus, but it isn't standards compliant with HTML.
