on Windows 95 in build 2001100903 (and all builds for many moons)

Go into Preferences -> Advanced -> Cache and choose "Every time I view the page"

Exit mozilla completely, then start mozilla again (that cache pref is not
activated unless you do so)
Move the mouse over the navigation buttons to get he mouseover effect. The
buttons will flicker.

The effect is greatly exagerated if you mouseover the navigation buttons while
loading a new page. The buttons can remain invisible for several seconds
That's very odd.  The HTTP cache validation preference should have nothing to do
with how ImgLib loads the chrome images.  Pav, any ideas?

How odd.  I can confirm seeing this effect, build 2001100903, Win98.

I see this behavior on Mac OS X build 2001-10-09-04-0.9.4, Linux build 
2001-10-09-04-0.9.4 and w2k build 2001-10-08-05-0.9.4, changing OS to all

I get the "flickering" behavior on other chrome elements too such as sidebar
tabs, it's rather nasty.  I've created an AVI that shows this if anyone needs
(800K, maybe too big to add as attachment here).  
Confirming Windows 2000 16,24,32 bit video settings.  Using mozilla win32
nightly build 2001102708.

Is everything including chrome going through the cache manager?

This WFM win XP build 2001111303, reporter are you still seeing this?
Yes, I still see this on Windows 95 using build 2001111303

I strongly suspect that this happens for the same reason that bug 108161
happens. After all, the images are being changed with javascript in exactly the
same way, its just that that bug deals with the symptoms of a webpage doing it,
and this deals with the symptoms of chrome doing it.
James: err no, images are not being changed via javascript the same way as with
webpages. It is being changed via css :hover rule though I think it is still
related to bug 108161.
this should have been fixed as a result of the checkin for bug 108161 since 
local images won't get reloaded as a result of validate_always, etc being set.
