When I'm doing a mosaic sequence, everything starts out ok. It slews to the 1st frame, focuses, aligns and begins auto guiding with a normal pick a star - calibrate - guide sequence. It then takes the required exposures.

The problem starts with the 2nd frame. It does a normal slew and align but then begins auto-guiding without selecting a new star. It tries to guide on "nothing" until it errors out. Only then does it select a new guide star and begin imaging. In the mean time it may have produced any number of unguided images.

Attempting to stop the guiding only makes things worse because it goes all the way back to re-calibration when that is unnecessary.

A second problem is that the job sequencer will not reset properly. It keeps all job status' at "completed" and will not re-run the set.
