click button bug

[TsFox]

When i tried to click some kinds of buttons(like OK,Search) nothing happend and the window doesn't close, just freeze.
This happen very often with eclipse Galileo. But it also happend with other applications.

The strange thing is if i use the shortcut(alt+<key>) the button works. And the cancel button always work.

I'm using karmic ubuntu 9.10.
