repainting when logging in

Hi,
I am a newbie to GUI programming and I was hoping someone could help
me.
I have a JFrame app that does not repaint when I log out (and then in)
of my Windows machine until I minimize and restore the GUI. Is there a
way of forcing the GUI to repaint when I log in again or have some sort
of background process that repaints at particular intervals? Please let
me know. Thanks!

doesn't JFrame (or JPanel) has a repaint() method or something? It should
also have a paintComponent() method.

I've only just started GUI programming recently. Currently having trouble
with a piece of university work. I have no idea how the two methods work, at
least that's a starting point. Hope this helped, if it's only a little bit.
Good luck

Which are not intended for fixing a broken layout. You never have to
call them by yourself for normal windows.

So why do you recommend them? See
