What version are you running?

2.3.2_rc2, with an Apple 23" display. I'll try some experiments tomorrow (it's at work, I'm at home now).

I restarted X11, and now it's back to normal: dimensions: 1920x1200 pixels (508x318 millimeters) resolution: 96x96 dots per inch I guess I'll just wait and see if it happens again. -- Richard -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
