I'm having trouble with Shi-painter. It loads just fine and I can draw with the pencil, but if I switch to another tool, it stops displaying on the work area, even when I get back to the pencil. I know it's still drawing because I can look at the preview with the layers and it shows the scribbles. I've made sure Java is up to date, so I don't think it's that, and thus far I haven't had the same problem with the other applets. Any suggestions?
