kmail and keyboard too slow - kubuntu 7.04

[Luca Ferrari]

I've had a look at top and vmstat outputs when this strange slow keyboard 
behaviour happened, and the only thing I noticed was that the CPU was 
unloaded and the idle cicle was around the 96% of the cpu time. I've tried to 
kill the processes listed on top of top's output (e.g., skype) but nothing 
changed and the mail composer still had this strange behaviour.
Any idea?
