i'm trying out the 2.5.2.1 beta - thanks for fixing those issues.
unfortunately i'm seeing some issue with the centering dialog hanging forever on setting the rotator angle. to be fair i saw this on 2.5.1 as well, i just forgot to report it. the problem is that it seems to be waiting forever for the rotator move to finish. just now it was hung like that - i had asked for an angle of 0.0 degrees and the initial solve indicated that the rotator needed to move from 5.5 degrees to 0 degrees.
when i looked at the equipment control panel's "other" tab, it was showing a rotator angle of 360.0 degrees. so i guess this means that the move was successful but for some reason the angle was reported as 360 instead of 0. (this is using @Andy 's optec ASCOM driver) for kicks i clicked one of the arrows to nudge the rotator by 1 degree, and suddenly the centering dialog woke up and moved to the validation phase. i'll post logs when the auto focus finishes. hopefully there is a rotator log as well.

edit: i guess it will have to wait tll the morning as 7zip is not happy that the log files are currently open.
