This code flattens ComboBoxes (even if they are ownerdrawn), EditBoxes and Checkboxes without any problems.
It also flattens OptionButtons, but the code is still buggy, please wait until the next version (but i need help on that part!!!) :-(

If you don't have vbwSubclass.dll registered then register it with regsrv32. See readme.txt for more details on this. :-((
