So, I've been having some issues with folding lately. For some reason, whenever my gpu finishes a work unit, it'll stop, and the client will log something about "sleeping" because of a failed unit or something like that, which is really weird because if I exit and start it back up, it'll do another unit just fine. I've double checked that the "one unit" selection is not selected, so that's not the issue.
I've tried both the Tracker v2 and the beta client you linked Fuga, but both of them do the same thing. Any ideas?
