It's not a full-fledged painting application. It's just something I wrote Saturday in about an hour or two. It's for my 2 nephews (3 and 4 years old), so I just implemented the functionality THEY need. I wouldn't really trust them with a TabletPC. I've
noticed they have problems with using a mouse (too big for their little hands), but they really enjoy painting with the pen of my Wacom tablet. EDIT: You have the source code, so you could add support for TabletPC yourself. Don't you love open-source ?
