i have a JFrame with a border layout with a JPanel containing JRadioButtons in north and a class DrawingArea that extends JPanel in the center. DrawingArea implements MouseListener. mouseReleased() has two lines of code one of which calls repaint(). for some reason it causes a second row of RadioButtons to appear below the first ones. when i override paintComponent() it also creates a second border around the DrawingArea. if i overide paint() instead it erases the original border. it only does this the first time after that it just draws rectangles like it is supposed to. i dont have a clue how this is happening. i implemented all the methods of Mouse Listener and i even implemeted MouseMotionListener also to no avail. here is some of the code.
in Jframe

in DrawingArea

When you override paintComponent(), be sure to call super.paintComponent(). That ought to fix this problem, actually.
