I've been through every setting on my FT-991A, JS8, FLDIGI and FLRIG and still I cannot have FLDIGI and JS8 open at the same time.  Even when selecting FLRIG as the "radio" in JS8, it keeps throwing a Hamlib error.  I upgraded to the latest Hamlib version and no luck.

At this point it must be the laptop.  I have an 8 year old HP running Windows 10.  Independently, all the aforementioned work great.  It would be nice on certain digital nets to have both FLDIGI and JS8 open at the same time.  

I don't want to wast anyone's time with this, but other searches in the group topics did not come up with anything for me.  Thanks for any feedback.
