VS 2010 breaks my keydown events

I have a custom control, a groupbo开发者_Go百科x, which reacts on key events on a assigned key. It is possible to remove this groupbox, as well as adding more dynamically. Havnt been any trouble in VS 2008 so far.

Two days ago i installed VS 2010. And i started to get multiple event fireing, and removing a groupbox did not remove the specific key events attached to it.

Where did it go wrong?

I use -= on the events present in the gruopbox code to remove them before removing the groupbox.

Are you still targeting .NET 3.5, or now .NET 4.0?

Possibly this is worth reading

or perhaps you always had a bug or a race condition...

Just guesses, I may be wrong.

Thats the strange thing.

I target the 2.0 framework for best compabillity with mono.

I checked old logs and no, no signs of racing there : /
