/*This is a resubmission of a bug report as requested
by Peter J. Allenbach OPCOM Consuntant 9.19.97.
Below I provide
an example of code which reproduces the bug.

if you run the program and then press and drag the
mouse over the red lightweight component you will
see that once the component is removed subsequent
drag events are not recieved by either the Frame
or the lightweight. If you change 'Component'
to 'Canvas' and make the component heavyweight
you will see the drag events are recieved by
the Frame after the removal of the Canvas.*/
