Could not make heads tails out of the requested test, but with 9.17.10.4439 HD3000 it seems that some times it works for 20 minutes just fine then not - a restart of the program or even the PC does not seem to matter if it is going to work or not - it just sometimes works for a while and then not. Memory management issue I would think - it is not laoding up the PC at all - I have a ton of resource not being used - it just seems to not make use of the memory for the program (sometimes) like 85% of the time. I have 8gig of 1333 ram it is not making use of anything. No expert but a guess.
