No, I cant see that this would interfere with normal message handling. In the msdn under RegisterWindowMessage http://msdn.microsoft.com/library/defau ... essage.asp It says that this function is

used to register messages for communicating between two cooperating applications.

and also that it

is guaranteed to be unique throughout the system

Also, I'd never heard of FindWindow having problems, but if thats the case I'm sure it wouldnt be too hard to communicate the hWnd another way.
