The first thing was to convert all the BMPs I made to actual Euphoria statements. As a result, the black colour didn't go "transparent" on me. I used display_image() and pixel() statements instead that were made from BMP conversion. The second approach when converting the BMP's became too much of a hassle was to select a wider range of colours to create a BMP in. Instead of selecting black, I selected a colour that was very close to black's RGB setting, but was not black. It did the job perfectly. Personally, I'd recommend the first approach even though it is a bit more work. Hope this helps! David Gay
