I had a conversation about this with one of the gtk+ win32 hackers.  The
Enter/Leave mechanism does not work on win32.  This is an underlying
issue in the win32 port of gtk+, which I believe is on the TODO list,
though non-trivial.

So bottom line, it's better to dispatch to the gui thread using
Application.Invoke, especially in the case of cross-platform
