Chris, thanks for your answer.
Yes, seems it only shows up on dual processor machines
I've had it running on my single processor machine for a couple of weeks now without any crashes.
Strange thing is that only one tester have had this crash and only once (he could not reproduce it)
and many have tested it on dual processor machines without any problems.
As I see it, the code is thread safe but well, it crashed once and that's one too much.
If anyone on this list with a dual processor machine want's to give it a try, here the beta is:
http://www.ronimusic.com/temp/asdbeta2.sit
The software is a CD and audio file player with slow down capabilities (the download is less than 400 kBytes).
Any crash logs would be appreciated ;-)
Thanks
Rolf Nilsson
