gst/games/gstpuzzle.c: - handle nav events differently: forward every event no matter if it was handled or not.
Original commit message from CVS: * gst/games/gstpuzzle.c: (nav_event_handler): - handle nav events differently: forward every event no matter if it was handled or not. - translate events You can now cheat by using navigationtest ! puzzle and moving the mouse close to the edge of a tile. ;)
