Calls to repaint queue up a request for paint to happen.
The paint does not happen immediately, so your listeners cannot depend upon
paint to clear out msg. The paint will occur sometime in the future.
However, multiple requests in the paint queue can be collected together, so
there is not neceesarily a one-to-one correspondence between calls to
repaint and executions of paint.

It is time to come up with a new plan of how to arrange your program.

Good Luck!
