Called whenever the timer fires.

There seems to be a bug in some RB versions:
If you draw into a window in this timer's action event, you may draw not in the window graphics port, but in the current graphics port. If you click on the menubar to open a menu, you draw over this menu.
To work around this you can add a line before drawing: TheWindow.Show
