Reassigning to "core" for evaluation.

tfrysinger, 
what is the version/build number of NB & JDK ?

Jara & Milos, have you seen this ?

I have never seen it because I do not use this drop down menu.

never seen it either. is it 100% reproducible? what is your jdk version? can you
attach your netbeans.app/Resources/Netbeans/etc/netbeans.conf file and the
~/.netbeans/5.5/var/log/messages.log?

I am running on the latest JDK 5.0 from Apple, running on OSX with latest
updates on a Mac Book Pro.

This reproduces fairly regularly for me - I can't give exact steps though. I do
see it every day. Anecdotally I believe it is something having to do with a
condition after something in the editor has caused a parse error. Could be a
class that doesn't have an import for example.

I only say this, because I generally have a fair number of classes open (10-20),
and when I see this it is because I have been working in one class, maybe doing
some refactoring or something, and I want to quickly move to the base class or
something like that.

I can reproduce this issue as follows:

1. Start IDE with several projects defined.

2. The last used project comes up, with several source code windows open. (see
attachment fig. 1)

3. Activate the pull-down menu. All is well.

4. Open the project tree for the current project node. (see attachment fig. 2).
Activate the pull-down menu. All is well.

5. Select a node within the current project under the project node (see
attachment fig. 3). Activate the pull-down menu. All is well.

6. Open the project tree for a different project node and select a node
underneath it (see attachment fig 3.). Activate the pull-down menu. The problem
appears. 

When the problem appears, the pull-down is completely whited out except for the
bottom and right borders (which are a black line and do not get overwritten).
This makes me wonder if it really is a renderer problem like I originally
thought it was - i.e. the renderer colors getting mixed up.

Note that this happens also with NB 6.0 M9 (but in even more places)

Some more information:

Even in a large project where this manifests itself, I can ensure correct behavior if I start up NetBeans with only the
Welcome panel open, close that panel, open the tree with the large number of nodes in it to get to the right package,
then start opening files. It seems that if the files are already open ahead of expanding the tree is when this problem
manifests itself.

Just to be clear; you're talking about the "Open Documents" dropdown?

I haven't seen this, but then I never ever use that dropdown; I rely on Control-Tab to bring up the document list (hold the control key, tap tab) instead which 
is easier from the keyboard.

We've worked aound some Mac bugs in the past by forcing use of heavyweight components (such as in the completion popup) and peers. Perhaps we could 
do something like that if Utilities.isMac() ?

Yes I believe so - it is the one I highlighted in my attachments.

Well - I just tried your control-tab suggestion but of course under OSX there is another problem. While the list does
come up correctly painted (an improvement over the dropdown), you can't scroll anything - as soon as you let up from the
control button it selects whatever happened to be currently selected and then just goes away.

This is similar to a bug that is currently in NetBeans 6 under OSX where the popup for code completion that comes up
after ctrl-space won't let you scroll or choose anything either.

There hasn't been any activity on this in a couple months. Is it being dropped?

-> future

guys, you already have a mac and i'm out of winsys for a while, reassigning

We still don't know how to reproduce, it doesn't happen for me, therefore it's almost impossible to find the bug and fix it.

can't reproduce, closing
