As I said in a previous email, the bug seems to have gone when I removed
the notification area from the panel. If it happens again, I'll also
watch my memory usage.

That said, the notification area could have had a memory leak.

I had a problem with my CPU a few weeks ago. It was stuck. I managed to
repair it and now it works fine. The laptop doesn't seem to over-heat.
More over, I could reproduce the bug with or without ACPI, and with or
without APM. So I don't think it's ACPI or APM-related.

I'll watch that. Thanks for the tip.
