Bob, I wanted to alert you that the APCC Pro fix that corrected the orbital tracking issue (sign reversal) has regressed. I had been using a BETA version from the developer (of APCC Pro) that corrected the problem. Unfortunately the newly released latest version still contains the problem. I'm offering this in case others are experiencing comet trails again as I did when I upgraded to the latest APCC Pro. I'm re-implementing the workaround in the ACP script AcquireSupport.wsc.
