I am running openSUSE 11.1 with KDE 4.2.1 on a MacBook Pro.

The whole screen freezes sometimes. I noticed that this happens only after viewing embedded PDF content in Firefox. (It is not happening always).
My firefox version is 3.0.7 and my acroread version is 8.1.3.

The machine goes very slow and does not respond to anything so that I was not even able to run "top" to see what is happening. I tried to ssh from another machine but it gets timed out.

Has anyone else experienced this problem?
