That's strange about the tool tips.  Is it only in Vue that you are experiencing the problem?  If so, I'd ask e-on about it.  It might have something to do with your video card.  If you have that problem in all applications & browsers, I'd google "tool tips" and see if you can find something.

I hope you get the problem solved!

By the way, I am not noticing any effects when I change the Object Size either and was hoping someone would answer your question.
