It works just fine, except for one weird thing: about every five or so units, it will go into an endless cycle of "Searching for Pulses". i've let it sit for a day or two (my usual crunch time is 6 1/2 hours), and it doesn't progress percentage wise, just searches and searches until I delete the current work unit and get a new one.
Has anyone seen this happen to them? Have I found a bug?
