Hi Matthew,
Thanks for the response. I don't have any shapes on the form. I have images but if I set the backstyle to transparent then anything that is white in the image's bitmap turn transparent and it didn't seem to help.

>Hi Tod. Seems to me that I had this problem before with textboxes too, and the same fix applied. Find all shape objects and make them identical in terms of backColor and BackStyle. I've set them to 255,255,255 and Transparent - which seemed to fix the weird backcolor glitches.
