I have a few combo boxes that I have applied some code to in order to make them wider when they drop down. The code is from this post:

http://www.vdsworld.com/forum/viewtopic.php?t=2829&start=0&postdays=0&postorder=asc&highlight=width+combo

It always works perfectly, until today. I have a user who has one Windows XP (home) machine that won't display these correctly. On the combo elements with this code, the machine displays them fully expanded, with no text in them, and no dropdown button. They still function, because I can begin typing and then click away from the combo, and the text I have typed shows up. But they are completely unreadable at first.

Is there an API name for the message in that post (above) that I could do a Google search on? Maybe someone else has had this problem. It seems to be a very isolated problem, but before telling the user to reinstall Windows, I would like to do a basic search for it.

Thanks for any leads -

The message name that goes with msg ID $352 is CB_SETDROPPEDWIDTH

Thanks. I can't find reference to any problem with it anywhere. I looked at my user's settings under My Computer>Properties>Advanced, and everything looked okay.

I guess I will just chalk it up to a one in a million error. (Or at least one in several hundred.)

I wonder if it has anything to do with XP themes... Did you include a XP manifest in your build?

Yes, there is a manifest.

I changed the theme from XP to Windows Classic and the problem was still there.
