copy this code and run the program..................
here when you run the applet and click on the menu, its hidden Beneath the bars that are drawn. but once you click on a menu item and come back it works fine... what is the problem with the code ?? how can i fix this???

Please don't cross post, it is considered rude.

Please continue with the original thread: http://www.daniweb.com/techtalkforums/thread77555.html

And do what was asked of you there (namely repost your code using code tags, in that thread).
