The problem occurs when the application is running in virtual desktop mode (in
full screen mode the problem doesn't happen).
Tested with several Wine versions from 1.2.3 to 1.5.12.

Native comctl32 doesn't help.

Steps to reproduce the problem (let's say with Wine 1.5.12):
1. create a new wineprefix and set up a virtual desktop
2. install the application, then launch it with ConvertXtoDvd.exe.
3. dismiss the trial reminder window and open the Settings-> DVD Specification
menu.
4. you should see 3 combo boxes here (Format, DVD Resolution, Aspect Ratio).
Open the first drop-down list (Format) by clicking on the 'down' arrow...the
list is opened fine.
5. open the second combo box (DVD Resolution)...it also opened correctly.
6. try to open the firstly selected drop-down list again (Format)...it doesn't
open any more
7. try to open the second combo box again: it doesn't open either
Once you opened a drop-down list, it won't open again (until you restart the
application).

In Wine 1.5.13 this behaviour changed somewhat: those drop-down lists don't
open at all (not even on the first attempt). The change is after
