Anyway it probably does not impact SGP frame and focus. Here is what i have found and how i use frame and focus.
I only use 'Take One', and this works just fine, based on advice from CN beta testers, as i am usually moving the scope slightly between takes anyway, i also use it to focus with my mask. I stay away from the continuous take mode because thst's all it does, take continuiously and not download. I suspect, given the amount of time it takes for one take to download and be displayed, that the downloads are over-run by the next frame and the necessary handshake can not take place.
I like to be able to alter the frame duration as i find say a 20 sec frame is good for small framing changes on nebulas, take one is good for this sort of thing. Make sure you are not saving those frames, there is a box to tick to save, i don't think its a good idea, these files are big and the less disc space used the better.
Check your camera setting box, you maybe surprised to see that even if your running usb3 it defaults to usb2 operation. I see this all the time, it doesn't interfere with my imaging but it does lengthen downloads from the camera slightly. This may also be the reason for the Continuous frame and focus not working.
So in a nutshell: Use Take One, it works and what's the hurry anyway. I woukd still do it that way even if continuous worked. Your alternative might be to frame and focus using Sharpcap as it can be a video stream if you want, however it coukd be messy switching apps for that, especially if your checking focus on filter swaps. The beauty of parafocal filter sets, focus once - this has worked really well on my Baader filters which are parafocal.

Hope that is of some use. Ray is using SGP, lets see what he says.
Cheers Glen. I'm not sure what prompted the new driver version, I just grabbed the newest ones of everything in the hope it would work.

I've actually got the opposite problem. Continuous download on frame & focus works fine, I can do it all day with the shortest exposures the camera can do. It's the main sequencing part that doesn't work.

I've checked the camera settings thing and it's using USB3, and was by default.
