/*If you have an editable JTree which is set up as a
DragGestureListener and DragSourceListener, then if you
triple click on a node to put it into edit mode, it also
ends up calling dragGestureRecognized to start a drag
operation.

Compile and run the test program.
Triple click on a tree node, and note that it
puts it into edit mode, and it gets in to the
dragGestureRecognized method. This happens on Solaris
and Windows. */
