First, instead of using paint(...) use paintComponent(...) instead.

Secondly, the paint can be called outside of your control. Like if another window outside of your application crosses over. Or, in this case, when you add the panel to the frame and it's also called when it's shown for the first time.

Also just FYI: I notice that in past threads you've been in a habit of posting questions and then ignoring the replies, of never acknowledging having read them. These two behaviors (cross-posting and ignoring replies) can often place you on the do-not-help lists of many forum regulars.

Much luck.
