I am writing a graphical applications where I would like to have dialog box
to pop up and input user information. My problem I am getting the dialog to
come up however when I am closing it out it is causing the frame to flicker,
losing the graphical integrity I created. There is a good chance I am not
calling or using the dialog box properly. I am looking for the simple sample
showing me the proper way to create, call, and close a dialog box  without
having a flicker.

Another problem In my program. When I mouse click on the screen my programs
will paint a spot wherever the click happen. After painting dots on the
screen if  I adjust the frame size in any way I will lose all my painted
spots. Is there a way other than recording all the X/Y coordinance and
repainting the spots; to have the frame to keep all graphical input. !!!

Thanks Jack
