> Tim, you've got tabs in your 3.3 patch.

Thanks, Antoine. I'll sort that out. (Goodness know how;
none of my editors use tabs).

> Other than that, I wonder why you wait for 100 ms in 3.3 but 10 ms in the other versions?

Ummm. Because they were written separately and I didn't
check carefully enough? I'll drop back to 10ms all round;
it never took more than 3 1-ms loops to fire in testing.
