- Not all interference is of the type that can be detected when you
- run your program. Stuff like having the user switch your screen to
- the back, or having a screen blanker wipe you out, or having other
- VBLANK interrupt handlers screwing with your timing.

-
- IMHO, a good solution would be to let the user know that the demo
- will take over the machine. For example, I currently won't try
- running any demo while doing a download or some other "live"
- process, because I know that the demo will zap the machine.

-
- So you're advocating not using the OS for double-buffering?

-
- Well, we'll see. After all, people can do demos on PCs, so I guess
- they'll figure out a way to do demos on AGA machines.
