I'm crashing when I goto the above url with the sidebar pane open, then goto "view" -> "sidebar" to close the sidebar (while the load is in progress). When I hit the menu item "sidebar," I crash. I have no clue what's going on in this code. The precondition that gets hit is: NS_PRECONDITION( aPos < aLen, "aPos >= aLen"); aPos == 1, and aLen == 1 NTDLL! 77f7629c() nsDebug::PreCondition(const char * 0x02518910, const char * 0x02518904,
