No, that's not intended. That's result of introducing dynamic tabulation and new text formatting tags. And it definitively shouldn't add that much spaces. I tweaked dynamic tabulation algorithm a bit, so check beta 2, it should address that: http://office.guru3d.com/afterburner/RTSSSetup700Beta2.rar Beta 2 also contain Unispace font distributive and automatically install it on RTSS installation. GUI glitch reported by Andy_K should be fixed now. Also I set default skin composition mode to layered with color key and light transparency to make it look more Metro-styled.
