19007 - Error with DHTML viewer demo page loaded.

Status: VERIFIED WORKSFORME

(Core Graveyard :: GFX, defect, P3)

Description

[Nick Silberstein]

With the DHTML page loaded in Mozilla (build 1999111608), one can not
access nested pull-down menus.  For example, items under Debug ->
Verification.

Another problem that appears with the DHTML page loaded is that the
back button functions incorrectly.  The previous page will not actually
render until the scrollbar is moved, or the window is dragged. The
animated 'M' also appears as an unloaded gif icon until the window is
dragged, or scrollbar is moved. This problem also occurs when one uses
the Go -> Back menu item.

Let me clarify - the DHTML page I was referring to is the one accessed when
one chooses Viewer Demos -> #13 DHTML from the Debug menu.

The issue is the compositor taking up all the available CPU cycles and locking
out the UI

Works just fine on the Mac. Plenty of CPU left. Must be windows event handling
problem.

Tried with 12/10/99 10:am build of mozilla on WINNT and it works fine for me.
I can access  under Debug->Verification. When I hit the back button it goes back
to the correct page. The throbber looks fine. Other changes may have fixed the
problems the reporter was seeing here.

Marking as worksforme.

I still experience this problem, testing with Build ID 1999121308,
fresh off the nightly build tree.  The DHTML verification page
works, but the Mozilla UI becomes unresponsive after hitting the
back and forward buttons once or twice in an attempt to go between
the Mozilla.org start page, and the DHTML verification test. WinNT
4.0, SP6.  I'm hesitant to 'Reopen bug', as I don't know the protocol
and don't want to step on any toes, but I can assure you this bug
is still present on this NT system!

With the Feb 01 build under Windows 98, I load the DHTML sample and use the back/
forward buttons. The functionality of these button are working without the 
problems first described.
