[Interest] Problems with Drag and Drop in Windows 7

[Samuel Gaist]

In my case they are reached. Are you building your application in debug or release mode ?

In release mode, it won't break. Furthermore a line like int n = 0; is likely to get optimized out.

If you want to have the correct behavior, do as said in the documentation with the acceptProposedAction()
