The remote desktop thing is easily explained (if you're interested) - Windows uses a virtual video device driver for remote desktop connections and disables the current video adapter for the duration of the RDP session - technically, for the length of your RDP session, there IS no Folding capable GPU installed (software wise) in your system.
I wish I knew so specifically what the problem was here tho lol but that's usually the way of things - when someone else has a problem, I can solve it - but when I have one myself, it'll be a PITA.
Having said that, that's probably a psychological thing though - when I come across a minor fixable issue on one of my systems, I just fix it and dont think about it - its the ones that are a pain which stick in my mind.
