I've had a few problems with the Lascaux Sketch v0.672...
It's eaten two pictures so far and I'm just wondering if I'm the only one who's had this problem? If that's the case then I should stick with the PaintBBS I guess.

care to elaborate?

Example...
Mmm.. I go to use a tool, or go to do something with a layer, the little window that opens up for the layer options, burn/dodge/screene/etc locks up. Then freezes.

sounds like something is wrong with your computer, not lascaux.
what operating system (and version), web browser (and version), and java version are you using?

hm
Must be the computer then.
Never given me problems before but oh well. No biggie :3 Was just wondering why that happened.
windows XP office thingie, IE 6, and java... hm. Not a clue

try upgrading to java 2: http://www.java.com/
