persisting graphics

[Pyro Joe]

hey, I have a form with multiple panels. when I switch a different panel to the front via the "bringtofront" method, and send the top one to the back via the "sendtoback" method, the background image for the panel I'm trying to bring to the front is not redrawn. I have tried invalidating and refreshing the form and it's client controls, have tried the same with the panel. I'm not having any luck. The images are imported resources, I don't think reassigning the image is the proper way, surely there's a way to persist the graphics back onto the background image of the panel. I'm thankful for your help, Stephen
