Now it is clear. If you pore over the internals of Windows notifications, you'll see that combos are completely different from lists internally. So I wouldn't even expect there being a flag, everything else is different under the hood. Lists existed in Windows 3.0, combos are from one or two generations later.

Unless your code actually uses specific features of combo boxes - and it doesn't look so from your descrition -, then I'd try refactoring and use the right control in the right place. If there is a technical issue stemmo,ng from what's in your code, then I can help with the refactoring perhaps.

You may have noticed that dev/doc work on Eu4.0 has gotten priority. My being off the net for 15+ days didn't help. I haven't started doing anything on win32lib 0.70.5.
