Hi Dieter,

Thanks for the reply.

John's problem is with GTK+ 3.4, and as gdk/win32/gdkdrawable-win32.c is not in the 3-4 branch, its difficult to see if this landed there?

I am better at release management (building, scouring for patches, choosing versions, etc.), but happy to test possible fixes, etc., so please shout if needed.


Regards,
Martin
