NSPopupButton displays black menu titlebar

[Stefan Urbanek]

Hi,

Try:
1. open any gnustep application which uses NSPopupButton, like in gworkspace 
preferences panel
2. right-click on the popupbutton - you will see a small ~4x4 pixel 
white-filled box appearing at the position where the bottom of opened 
popupbutton should be
3. open the popup button with left-click and you will see a black bar at the 
bottom of expanded popupbutton, like that one drawn for main menu

If you do this to a popup button with just one item (gnumail compose window, if 
you have single transfer method or single user profile), then by left-clicking 
(after that right-click) on it will start dragging the popup button with the 
bar.
