Confirming bug with Mozilla trunk build 20020508xx on WinNT

This has something to do with the cache. If I get into a state
where both selectboxes are missing, Reload does not help: 
but Shift+Reload makes the selectboxes show up.

Similarly, if I go into Edit > Preferences > Advanced > Cache,
and clear the memory and disk cache, then hitting Reload alone
will make the selectboxes show up.

Don't know the exact component for this, but it's not JavaScript Engine.
There are no errors in the JavaScript Console. Reassigning to 
Networking:Cache as a guess; please reassign as necessary; thanks -

It's unlikely this is a bug in the cache, but rather one of the cache clients is
possibly mis-storing data.  What causes the boxes to disappear in the first
place?  If that gets saved in the cache, then it's no surprise it won't get
fixed until a shift-reload or clear cache occurs.

This should probably be a different component.  Radha, is this related to wyciwyg?

I think this is a problem in rendering. Once a model is selected, a new page is
loaded, but the section that has the selection box is not rendered. The button
underneath it, "Handy anzeigen" is rendered over the text above the selection
box. However, if you do a view-source, you can see the source for the selection
boxes. so, I think cache has the right source, but somehow it  does not show up
on the screen. I do not see any  document.write() for this part of the page though.

Reassigning to Layout, but maybe Widgets would be a better choice.

WFM WinXP 2003012908.  Am I doing something wrong?  Here are my steps:
1. Go to http://www.xonio.com/application/handyvergleich/handyvergleich.html
2. Select LG Electronics in the left dropdown (the "Hersteller wahlen" one)
3. A new page appears with "LG Electronics" on the left and a list of choices on
the right.

From reading this bug, that seems like the right behavior.  My impression is the
behavior you were seeing was that in #3 both dropdowns would disappear.

Marking WFM using 20040206 in WinME (Win32).

Reporter, if still a problem when using a current build, please re-open or
create a new bug.
