This seems dangerous, changing the window size will potentially send messages to other threads, so doing it inside the lock can cause deadlocks.

So I should unlock before I change the window size?

Probably, though I guess that depends on what the Windows behavior is with windows and multiple threads.

I have to read up the msdn and propably write tests for it, but there are some methods which must be called from the thread that created the device. SetDisplayMode and RestoreDisplayMode are 2 examples, I *think* it applies SetCooperativeLevel too. It would make sense because SetCooperativeLevel is the method used to turn on multithreading protection.
