Earlier tonight I had a sequence that completed and went into the end of sequence actions as expected.
I saw my telescope park and the status bar in SGP said “Parking telescope…”, but it just stayed like that for several minutes without proceeding the the rest of the actions like turning off the camera cooler. Nothing in the UI responded to mouse clicks and the app was frozen.
This was similar to the UI hang we saw in the earlier 2.5.0.x betas that would happen when a sequence was paused. I was able to get out of it the same way: using Task Manager End Task caused SGP to put up a dialog box asking me if I wanted to exit with equipment connected. I clicked Yes, and yes again when prompted to turn off the camera cooler, and SGP closed.
