fixed three regressions that crept in due to implementation of moving gop objects by tag. one of them manifested itself when an object was altered as gop and a sub-patch pops up asking to discard changes made to it. upon returning on the main window with the said gop, due to redraw objects were not reselected so dragging the object would not redraw properly even though it could be displaced, resulting in a seemingly stale gop object (in actuality it was simply displaced by being dragged while its visual content did not displace). Also, excessive stdout errors regarding redrawing gop resize handles and possible menu edit update has been dealt with.
