Windows: Control key not recognised when remapped with SharpKeys

Hi first post here… to bump this issue. Bought renoise a while back but never had time to learn it. Just coming to it now, and my Ctrl / Caps swap (done through windows registry which works everywere else) is not working in Renoise. Total workflow problem for me and sadly means I can’t use versions after 3.1 (which works great in this regard).
Please can this be fixed so I can enjoy using this lovely software?
Thanks
