One of my applications highly depends on transparency, but the .NET way of making forms and controls transparent seems not be guaranteed. I have run into situations when transparency just does not work.
To name two:
1. Some nVidia cards and some drivers of them.
2. Starting video programs such as Media Player.

Do you think there will be a better way arround to make forms and controls transparent? Or should I warn the users of known and maybe unknown situations that the program will not work?
