What? You got VS 4.3 before me! That's PREPOSTEROUS! Right I'm off to bitch & piss & moan at Simon & Thomas for not giving me access to it first!
Just joking.
Visioniare Studio 4.2.5 is the current public version. Is there an option to run in compatibility mode? If there is, try setting it to windows 7 or 8.
VS is known to be a little buggy with windows 10, but should probably be ok in 4.3 - at least I assume it will be a lot more stable - there will also be support to export for additional platform targets too - as you probably already know if you've scrolled down the new VS homepage thing.
