It seems the beta version of the folding client doesnt like my CPU as ive left it for over an hour and its not completed 1% yet, so i reverted back to the GPU tracker and that client does the same whilst the beta client is open!
I used to get that with GPU Tracker when it crashed,or the GPU overheated then crashed. The display will show no movement in folding progress, but the CPU/GPU load and fans were still whirling, and looking at the log text file shows that still still kept folding in the background.
Reboot.
