1.5.8.20 beta reports on starting "An attempt was made to load an assembly from a network location which..."
It reports that commands are being carried out, but tests using NP++ show no output for Key Press commands (other tests not carried out). (Just read Pfiels's report that commands are not executed if listening is disabled, which was the case during my testing). Will re-try testing if needed.

These problems don't occur with 1.5.8.18 beta
