Hi,
This is pretty interesting. The other day I tried enabling compositing mode for windows on XP, to see if it got rid of some redraw/flicker problems we were having ( notably with lists ). It does fix it, but I got what I take to be the same behaviour with the preview described in the first post. I imagine Vista has the compositing mode turned on all the time, which is fair enough, it should be. Unfortunately even if I can find a fix for this behaviour, turning on compositing in XP noticeably slows things down.
Regards,
Jo
