WoW Weirdness

[Jayhawk]

I've been having some strange problems with the game since... a couple days (possible a week). I log on, which works fine, then I watch the blue bar move to the end of it's box on the load screen and...it just sits there.

I know the game's done with loading as I can ALT-TAB out of it (which it refuses to do while loading). This happens both with and without addons loading. Occasionally I do get in, and the game seems normal. Then today it lost the content of the minimap and when I got back to the character screen is was a single solid colour, with just the buttons and the labels showing.

Suggestions?
