Looking for some advice here -- I am having a heck of a time getting Shi Painter to work properly. If I start out drawing, then I can see those marks. But when I switch to another tool, those drawing marks are invisible. (Now, I can see them what the other tool did, if I flip back and forth from floating windows to main window.) Any ideas on how to get Shi Painter to work properly? (I should add that the problem is present in Chrome, Firefox and IE too. :-/ )

I just tried it.. and had no problem.. I can't imagine whats causing that.. maybe uninstall and reinstall your java?
