[Gambas-user] Problem with tableview when in edit mode

OK, I understand the problem.

The TableView is designed so that editing a cell must be decided in the Click 
event. Otherwise, if the Edit method is not called during a Click event, 
keyboard events automatically jump them.

You must call the Edit method inside the Click event, not the GotFocus event.

Before, keyboard events never ignored cells, so things were working normally.
