Can't run an "Event"

I noticed a similar thing Monday night. I was going to image some geosynchronous satellites and turned off autoguiding. (autoguider = none). and had set the mount tracking off. When I went to run the sequence, the sequence said complete. After a minute of thinking, I disconnected the scope in the sequencer panel and all went normally. I still had the scope connected in TheSky6, but disconnected in SGP. I suspect that there is a check for tracking or something in SGP that results in the sequence complete message.
