I am running Interpid on a Dell XPS M1210 laptop with an nVidia GE Force Go 7400 card. I have been sucessfully using AWN for several weeks. Today I installed the new nVidia beta driver version 180.06 because it has a number of bug fixes.
I am pleased to report it has eliminated the white box problem with AWN (as well as several others not related to AWN). After testing all the AWN applets, the only one I found not working was stacks. The problem only appears when the stacks applet is set to display with the default or trasher layout. The curves layout still works. I ran it in a terminal and was able to capture the following output:
Traceback (most recent call last):

After doing additional research I discover that the problem was NOT the nvidia driver. Shame on me for putting my guess as to the reason for the breakage in the bug title. Please change the title of this bug or reject it and I'll open a new one.
The real problem was that one of the files in my launcher directory was a desktop shortcut without an associated icon or pixmap. (Ironically, the desktop file was for nvidia-settings which has move its pixmap in the beta driver).
It's still a problem with the stacks as I believe the lack of an associated launcher icon should not cause it to fail.
