The first thing that happened was the whole screen was painted maybe black pixel by pixel which took about 20 seconds. Then the whole screen was painted maybe white, or maybe halftone which took another 20 seconds then each window was painted about three times it was extremely slow. Plus a bug in my font code in BitBLT which caused it to say Welcome to SnailTalk.
