I started SGP, connected equipment, and ran auto-focus. After the AF completed (AF dialog closed), the status bar still said “auto focus running” and the Focus Control module AF button said “Stop”, but clicking it had no effect and I could not get out of it without exiting SGP.
Can you both please reattempt with the beta that was released earlier this evening. There are a couple of fixes in the AF code that should prevent hangs.
I have added a lot more logging to the next beta. If I could reproduce this even once, it would be a lot easier, but this is how we will need to handle it…
