# To subscribers of the xforms list from "T.C. Zhao" <tc_zhao@yahoo.com> :
Sorry for taking this long to respond. As usual
Steve is right about idle_delta affecting
the canvas although I haven't figured out how
(and why). I'll start digging into the code.
In the meantime, you can workaround the initialization
problem by setting the delta to some small value,
then when you know the initialization is finished,
you can reset it to something reasonable, say, 50 millisecond.
(incidently I also think the delta should not affect
the *behavior* of counters either. It may affect
how many times a counter is checked, but the repeat
rate *should* be based on absolute time, not
how many deltas. sigh).
