I'm not sure what Desktops v2.0 does, but maybe try Fences by Stardock instead? That works well with Start8 on Win8.1. As well as making the fenced in areas, it allows dragging desktops sideways to setup multiple desktop views. If that is what the other program does, maybe that'll work for you?
It's the most simple multidesktop app. No dragging stuff between desktops, etc. just changing desktops (ie. sets of open windows).
Thanks for recommendation. I'll take a look at Fences, but I'd prefer free software with as small footprint as possible.
