Okay, here's the problem. I'm drawing a graphic image in a window which can be moved and resized. I'm using a SMART_REFRESH window, so the only thing I have to worry about is when the window is sized larger, especially after it is first shrunk. If this happens I get big patches of background where (part of) my image used to be. I'm drawing the image using WritePixel(), and I'm not saving the image in memory or anything, so it's on its own once drawn to the window. If I understand the manuals correctly (which I doubt), Intuition will store clipped portions of my image somewhere in RAM. I'd really like to know how to get these back. I know to use Begin…EndRefresh(), but what do I do inbetween? Can I use some layer functions here? I hope I don't have to use SIMPLE_REFRESH or SUPERBITMAP here, though that's what I'm being told. Yecch-o!! Help me please… /brent
