IU-ish question... or I'm a idiot and broke something!

[Isaria]

The other night I was wrapping things up and getting ready to log. I dropped some things on my mouse and keyboard and when I logged back in last night I don't get the mouseovers in my inventory any longer.

I can right click and hold to get the item details, but I don't get the item name from a simple mouseover. Any suggestions on a fix? I can't seem to find anything obvious in what I may have done. I realize it's not the end of the world, but it's a bit annoying.

Thanks in advance!
