Could you linux users who were also suffering from this bug give it a try ?
As promised a few days ago I did try this again. And it works as expected.
One strange thing I have is : each time I reenter the choice control every entry I have selected before is now unvisible, it only becomes visible when I (pre)select it with the mouse or up/down keys. I wonder if this is more general, or it is just my display settings (linux suse 10.1 64 bit) ? in the case this is moe general, well then one bad thing get's replaced by another bad thing :-(
I noticed something similar, also I can't really reproduce it. It only happens sometimes when C::B lost its focus and I switched to another virtuell desktop. But this is far less problematic compared to the problem with wxComboBox.
