Description Dave Camp 2002-05-01 01:43:10 UTC 
I'm seeing a pointer grab when ending some drags.

To reproduce, apply the attached patch to testdnd.c.  Repeatedly and
quickly drag from the button to the trash can.  It helps to load up your
system first, or run it on a slow system.

After awhile you'll see a pointer grab.  It looks like the grab is
happening on line 2439, after a XdndStatus event is recieved after the drag
has been ended and the pointer ungrabbed.  

The attached patch just switches the action sent to gdk_drag_status every
time, to increase the chances of line 2439 being hit.

Nautilus' icon view seems to be able to trigger this fairly easy on my ultra 2.

        * gtk/gtkdnd.c (_gtk_drag_source_handle_event): Don't
        call gdk_pointer_grab() to change the cursor if we've
        already ungrabbed on button release / escape.
