It's moving the cursor around. I have seen it on Debian 6.0 and Ubuntu
10.10. When I get round to it I'll give a -Q recipe. Do you have font

faces. I don't know if that's the problem.

There are two types of people in this world, good and bad. The good
sleep better, but the bad seem to enjoy the waking hours much more.
