Thia ia the perfect software for Screenwriting. It lays out the correct format, and has so many time saving devices. It comes with an easy to follow users guide on the CDROM, complete with a tutorial. The thesaurus is more limited than that on say WORD, as is its vocabulary which leads to a lot of red lines under words it doesn't know, but you can tell the dictionary to "learn" words. There are some features I have yet to understand and some which I'm not so keen on, but overall it's made a huge difference to writing my screenplay.
