Hi carpman,
Since Tattoo is a Blitz3D application, it does try to hog all the blitz related resources (not to mention fig loads of Video Memory). So I wouldn't recommend running it alongside other Blitz programs (expecially full screen games/apps).
It should also be noted, that Tattoo when closed will hide itself for a few moments and clear out it's memory buffers etc.
You should allow it time to finish this before running a blitz program, usually about 10 seconds will be safe.
