Please describe the problem:
If the "Window List" GNOME-PANEL applet is on the left side of the screen, it's about 150 pixel wide and there are about 10 windows in the list, the "buttons" for changing to the windows are resizing and it's hard to click a button. It's resizing from big button to small button. When small buttons, there are 2 columns of buttons. When moving and clicking it seems to be tickled and resizes all the time.

Steps to reproduce:
1. Panel on the left side
2. Window list in the panel
3. panel is 150px wide
4. 10 windows in the window list
5. Moving over the window list

Actual results:
Seems to be tickled, resizing like crazy

Expected results:
Not to be resizing all the time I move over or click it

Does this happen every time?
Until now, yes

Other information:
ubuntu 8.04 up to date.
If I resize it to smaller it happens to hang and I can't use any panel any more. Until ctl-alt-backspace
