mouse event handling

[Miven Dooligan]

I am having to make this tweak in screen.c
for 3 years since I keep playing with mouse stuff,

other panel doesn't work.

-    if ((event->type & (GPM_DOWN|GPM_DRAG))){
+    if ((event->type & (GPM_DOWN|GPM_DRAG|GPM_UP))){

         if (panel != (WPanel *) current_dlg->current->widget)
             change_panel ();

     }

Anyone know a reason why button up shouldn't know its location?

Peace.
