I don't have an answer, but I do have a couple
of suggestions.
Instead of "startPoint = (*startPtP);" try using
MemCopy. Does the behavior change?
Also, I saw a later message suggesting that
the Snd calls were overlapping and masking
out the initial alarm sound. I seem to recall
something similar. Try using an alert instead
of sounds for your diagnostics.
