Work Unit does not suspend

My system is set-up to keep workunits in memory, which is not normally a problem, but with Einstein the work units do not suspend. The workunits continue to eat up CPU cycles (with out processing any of the data) when suspended.

This causes the CPU to run 2 Einstein tasks continually 24/7 whether I am using the computer or not, and 2 + 2 other BOINC tasks when it is not scheduled to run. It is killing my effeciency.

Any ideas?
