Much appreciate your time on this. I guess it is a new feature of the browser in HS2 that it can show and play the other instruments from the VSTi collection (or at least some of them). It then shows the instrument inside the HS2 window for editing sounds etc. Just a bit annoying to be shown that feature and then denied access to it via the CMC. Hey ho !
I’ll add it to the requests / wish list 
Thanks again
