I have a graphics application written in Visual C++ Standard and Windows Win32. I draws simple pictures using only a few diferent pens and brushes. It works perfectly on NT but on Windows/ME the colors go all black and the screen text disappears after only a few repaints. I suspected object problems but have checked very carefully, many times, that they are all destroyed after use and before another is created. Any hints as to where else to look for the problem?
