I have timers to do this. The problem I'm having is that as more text is drawn into each canvas the slower it gets. I'm sure there's a better way to do this. Is it possible to have timers in threads? I'm thinking that if the window could just do the drawing and the threads handle the logic that might be better. Am I on the right track? Is there a better solution?
