Build ID: 2000042608 This is most easily reproduced when using the Known Bugs link on the Debug menu, though once or twice I have been able to do it just by typing http://www.mozilla.org/quality/most-frequent-bugs/ and pressing enter... Steps to Reproduce: (1) Choose Known Bugs from the Debug menu. (2) Wait a split second, then begin to drag the sidebar to the right (even if it's at its maximum length). Actually, I have DSL so I begin dragging right away...you should begin dragging right as the content area turns white before the page actually loads. Result: crash Don't be quick to mark as wfm, please... I realize it's not easy to reproduce, but I've been able to do it quite a few times that I believe it warrants a filing. The GPF info is: MOZILLA caused an invalid page fault in module GKHTML.DLL at 0167:01b0be6a.
