Tested with Linux build 2000060908. When I open a window on Mozilla (either the first time or to launch an additional window) it opens so that it is mostly off screen -- usually to the lower right of the screen. I am running RH 6.2 and KDE 1.1.2 with smart window placement policy.
This didn't used to happen for Linux build 2000060713.
Confirmed for build 2000060908 on RH 6.1 for KDE 2.0 beta build 20000608
Most likely caused by bug 42035
over to xptoolkit widgets and pav for more investigation.
