Button Close or Help Problem

[semsphy]

Hello guys,

I installed the ubuntu 11.04, it's look great. But right now, it's a little wired for me because when I did right click the to choose the property of one file, then I tried to click the button close or help, it was seem no action. Does anyone met the problem like me? Thanks.

Can't say that I've ever experienced this problem.

Have you tried logging out, then logging in again?

I wouldn't think that this is a hardware problem...
