Mac build 1999-12-02-12 M12 Win build 1999-12-02-11 M12 Linux build 1999-12-02-08 M12 All platforms: This is somewhat difficult to reproduce, but it happens on all platforms today. Steps to repro: 1)Launch Seamonkey and login to IM via Tasks-->IM. 2) When standalone comes up, drag it to the right of your screen. 3)In Standalone, open all groups in List Setup Tab (causing Vertical scrollbar to appear) 3)Scroll through the List Setup tab (move tack to top, then to bottom of scroll bar) 4)Click on Online tab and scroll thru it in the same fashion. 5)Move MyPanels tab up to the top of the standalone till the buddy list above it is gone (Vertical scroll bar there disappears). Let go of mouse button. 6) Now click and drag it the MyPanels tab back down again so you can see the buddy list above it in the Buddy List tab. 5)Scroll through the List Setup and Online tabs again the same way you did in steps 3 and 4. Actual result: You will crash Macsbug log follows: MacsBug 6.5.4a6, Copyright Apple Computer, Inc. 1981-98 PowerPC unmapped memory exception at 3F800000 2-Dec-1999 2:55:00 PM (since boot = 13 minutes)
