problem with fullscreen

[Hoang-Vu PHUNG]

Hi,

I have following problem:
In a application, i do a roll up, then fullscreen the application disappears
completely. I still see an icon on the bottom bar but when i click on it
nothing happens.

So how to make the application back to the previous state - which means
visible again.

I'm running with pclinuxos xfce desktop 2010

Thanks for any help.
