Flipping between frames?

Hello,

I have got a StartFrame-class that shows up a frame where a user can make
some selections
and when done with this another frame is opened from StartFrame-class for my
main-application.
I use StartFrame.hide() to make the first frame invisible. Later when the
user ends with the
main-application i want to close the main-frame and make the StartFrame
visible again.
How can i accomplish this? Besides, yes i know about modal-dialogs etc...
but i want to
have 2 independent frames.
Thanks in advance,
Jan
