I have investigated this problem further. It is definitely the case that autoguiding will not resume after the primary ccd downloading is done. If I try to force it to re-start Autoguiding nothing happens. The driftplot is not cleared and re-started, even though the status window says autoguiding started. The only way to be able to Autoguide again is to Disconnect, Stop Indi, Start Indi and then redo the Calibration.
If I am not using the primary ccd I can start and stop the autoguiding without a problem.
Since my Celestron telescope driver is not working I have had to struggle with the telescope simulator in order to get a debug log, which I have attached.
Here is what I did:
1) I took a picture via the primary ccd to ensure it was working OK.
2) Calibrated the guide ccd and then started guiding.
3) Took a picture via the primary ccd
4) after downloading the picture the guiding never resumed. The drift-plot froze.
5) Tried manually to stop and start the guiding a couple of times but nothing happened.
6) Disconnected and stopped indi
