Drawing problem with ComboBox

[Andreas Höschler]

Hello all,

I have a combo box in our app with setUsesDataSource:YES. When I pop up 
the combo box, some rows are blank though they shouldn't. The method

- (id)comboBox:(NSComboBox *)aComboBox 
objectValueForItemAtIndex:(int)index

returns correct values. Now it gets weird. When reproduce the problem 
(popping up the combo box table view) and then use gimp to make a 
screenshot, on the screenshot all rows are shown correctly while they 
aren't in my app. This leads me to think that it must be an issue in 
back. Probably gimp causes all windows on the screen to redraw before 
the screenshot is taken. We have built back (latest cvs) with

        ./configure --enable-graphics=art
        make
        make install

Any ideas? This is on Solaris 10 with GNOME. But I bet this can be 
reprduced on any X11-based system. Thanks a lot in advance!

Thanks,

  Andreas
