This winter I've had issues with my EFW2 filterwheel not connecting first time in SGPro. I have to turn the power off and on again and then it connects. Then it's fine for the rest of the evening. When I used it a couple of years ago I was using AstroArt 4. I didn't have a problem, with that or APT which I also used at that time. I may have upgraded from W7Pro to W10 Pro over the period, I can't remember.
Thanks.
I will admit I haven't upgraded Atik Core recently but I only use the Ascom Driver.
