Using the current build of CX Office, Topstyle works pretty well. You need to install IE6 (and DCOM95) before the preview function works.
Things that are noticeably wrong are:
Fullscreen previews - opens up a tiny little preview window that can't be resized.
Minimize/Maximise window - the only option in the window titlebar is to close.
Side panel scrollbars - when the window refreshes itself, sometimes the scrollbars in the side panels go all wierd for a sec, then correct themselves. Nothing major, but it's a distraction.
Display corruption - occaisionally, switching between editing tabs will cause the tab bar to corrupt. This also corrects itself after a moment.
If anyone has any questions about running Topstyle on CX Office, leave a note here.
