Vray Windows, I can't move them once open! Help

Continuing the discussion from Vray Buffer Window won't move to 2nd screen:

A slightly different problem, I have recently moved to windows. Both Vray windows Asset editor and Cosmos windows once open can’t be moved around the screen. I’ve come from OSX and haven’t had any issues like this, Looks like i’m green to something! Any thoughts? I have uninstalled both vray and skp etc but no change.
