No, that's probably a problem with your Dell notebook.  I've had two Dells
do it, and they do it under Windows as well.  I was sure it was a FreeBSD
psm bug for months and months, and spent days hacking on psm trying to
figure out what was triggering it.  Then one day I was sitting in a
meeting at our offices in Santa Clara, and a whole room of people were
typing on Dells, and about once a minute someone would go "Damn mouse".
Then it clicked :-).  I wouldn't rule out a recent FreeBSD change doing
it, but given my experiences I'd think it more likely to be a hardware
issue.  it went away each time I replaced the motherboard, but came back a
few months later, suggesting wear-and-tear.
