How can I prevent my program from clearing a panel when it repainted.

You cannot. The panel has no "memory" of what you have drawn on it. When you
cover it with another window and then uncover it again all that was on it has
to be redrawn.

Use a TImage to draw on, it has such a "memory" (since the image.Canvas
actually draws on an off-screen bitmap which the image redraws on sceen as
needed).
