>I have a bunch of PNG images that I've attached to command buttons and forms over the last couple of weeks and they all looked fine. Now, for no apparent reason that I can see, the transparent areas of the PNG images are no longer transparent - they show white instead. Could someone please tell me what could possibly change within VFP to cause this arbitrary change?

Make sure your runtime .DLL's are the most current. I seem to vaguely recall something about VFP9 and Service Packs adding PNG support or transparency support or something.
