ZWO ASI1600MM-Cool Image Download Hanging

I reverted to ASCOM driver V1.0.2.5. and that seems to have fixed the problem for me, at least Frame and Focusing is working again. I have shot some quick test images that I need to check. At least it is not stuck in constant download state that can only be stopped by shutting down SGP.
I am tempted to rollback to SGP .14 as I had that running flawlessly for three weeks when I first got the ASI1600.
