How do I prevent message box from erasing lines?

I have a program where lines are drawn based on values that are calculated in a calculator. A message box appears with feedback. However, the message box erases the lines that are drawn if I drag it over the area. Since the box appears in the middle of the page, it always manages to erase something. How do I prevent this? Two solutions are to: 1) Make the message box an overlay or something akin to it, oe 2) make the message box automatically appear in a fixed area. Any suggestions on how to do this?????

Set the form's/picturebox's .AutoRedraw property = True.

Good Luck

Another method is to place the line drawing code in the picbox paint event. This is only really necessary if the picture is going to be changing. Otherwise crazed-lunatic's solution is better.
