Fixed an error in the GUI code that checks for double-clicks.  The button used in the first click was always being set to the left button, and checked against the left button in the second click.  This is now fixed -- the button actually used in the first click is recorded, and it is compared against the button actually used in the second click.  The two must match for a double-click to be generated.
