Tips on importing screenplays

As the script formatting is still a little buggy in the Scrivener beta with text going vertical. I thought I would type in Celtx and import into Scrivener. Scrivener recognises everything as general text. Even when I re associate script elements the formatting is still off.

Any tips on combating the vertical text problem and/or importing scripts into Scrivener?

Ignore yellow background. Not a feature of Scrivener yet. Changed my Windows theme to limit the white editor/full screen background burning a whole in my retinas.
