Reid:
The offset is probably caused by using heavyweight and lightweight
components together. You don't post the containers (i.e., Applet of
JApplet, JComboBox, etc.). There's a really good article on this at the
Sun site. Used to be referenced in the hints_and_tips docs with
JBuilder back when Swing was new and folks porting over to it kept
running into problems.
