I think the proper solution is to instruct GTK2 to use the MOUSE_UP
event, but meanwhile QueueAsyncCall will not be the solution as when the
AsyncCall will be processed grid will be still waiting for MOUSE_UP, so
my solution would be add a MOUSE_UP and MOUSE_DOWN handlers, something
like this in pseudo code:
if SelectChanged then Form.ShowModal();
