In my 01/20/2000 WinNt debug build, I'm seeing assertions being thrown from code called from nsBoxFrame::SetInitialChildList(). I can continue passed the assertions but they are annoying. Here's the assertion I get when bringing up the Prefs dialog: NTDLL! 77f7629c() nsDebug::Assertion(const char * 0x01774f50, const char * 0x01774f30, const char * 0x01774f04, int 2764) line 186 + 13

I don't think QA will see this problem in the Commercial OPT builds.

BULK MOVE: Changing component from XUL to XP Toolkit/Widgets: XUL. XUL component will be deleted.

This was a bug in layout. It is now fixed.

please ignore, massive spam giving jrgm@netscape.com backlog of XPToolkits resolved fixed bugs to verify
