I'd banned CPW from Rapidroid because it used to keep "ponder on" all the time whatever was the GUI setting. This fixed version promises to heal the issue. I'm happy i can push CPW to the battlefield again given that compatibility wise i'd seen no issues at all other than that ponder problem.

P.S.: Just tried the benchmark test on dual core RK3066. Unfortunately the issue repeats. The engine starts to ponder as soon as loaded, even at initial position. I see one core active before first move. Importing another engine frees the cpu. Again, CPUstats is a great tool to verify core usage issues.
