Redraw problem with comboboxes on tab controls

[Michael Jung]

Hi,

I do have a couple of windows programs that have comboboxes in tab controls, 
which have redraw problems. There's a small test-program appended to this 
mail, which exhibits this problem. It's probably a very simple problem, but I 
have no experience with wine's GUI code. So if someone who is familiar with 
the combobox code could have a look at it, that would be nice.

Bye,
