Subject: Re: [Jprogramming] Trouble making patter for a color cube

Nice!

As an aside, I have noticed a problem: if I click on the "OK" button for the 
shader demo, while the demo is running, I'll get a second instance of the demo. 
The cube in the first instance freezes, and the cube in the second instance 
spins faster.

Worse, when shutting down the demo, I get into an infinite error situation and 
have to shut down J from the outside.

I think the issue here has to do with the use of the timer. I don't think we 
have an option to make timers in a locale, and we haven't defined any 
dispatching system to support multiple locales. Perhaps the thing to do here, 
until we can come up with a better approach, is refuse to run if the timer is 
already in use?

What do you think?

Thanks,
