Can you send me your script and tell me exactly which decoder
software you use (version)?

I did not, although I can not exclude the possibility that there
might be problems left in the multitasking part of WarpOS. I need
a reliable way to reproduce the problem, otherwise I can't find
out whether the problem is really WarpOS' fault. Up to now there
was no way to reliably reproduce multitasking problems, at least
I didn't hear of any.
