Hi, I am trying to implement drag and drop. Currently just trying to get the destination working. I have the basics working, but if I attempt to do custom "drag-motion" validation and I call gtk_drag_get_data() the Xserver locks with a drag cursor. The only way to get out is to Alt-F1 then kill the xserver (just the program doesn't unlock). Has anyone encountered this before?
I am probably missing something simple. Here is my code, thanks.
