Hi sometimes when i use the desktop exposé function it only shows the desktop for a couple of seconds, and sometimes it works, showing the desktop as long as i want.
I havent localised when, what apps are running when it happens. I first thougth that it happened when i had a ssh connection open, but i tried that now, and it worked fine.
i also sometimes use vpn... but i dno't know about that either.
The first time i noticed it was when used the i-installer to install TeX (LaTeX etc.)
then, the terminal was open, but not running something. Now the problem occourred, when i closed the Terminal it worked normally.
But sometimes the 2-3 seconds occour even if the Terminal is not open.
Havent had any problems in a couple of days though.
