It's long known that having indicators underneath transparent graphs causes quite a slowdown. Is that your case or are the indicators unseen until you make the graph invisible? I guess the controls aren't intelligent enough to know if they're really visible if the visible flag is set true and the window is open and the same performance hit is applying. If you're using the graph to hide controls until needed then the tab control is the way to go. Manually showing and hiding controls is a pig to do in the first place, and a pig for you or someone else to maintain. You can hide the buttons of the tab control if you want to present a "wizard" style interface. -- Dr. Craig Graham, Software Engineer Advanced Analysis and Integration Limited, UK. http://www.aail.co.uk/
