I knew this was an issue in SP2.0 and thought it was fixed in 2.1. Not on my machine. I read it may install wrongly on an NT4 machine, but I'm running WinXP SP1. After 'Save as' it's 'Generating PDF file' but just afterwards it says 'An unknown error occurred during the creation of the PDF file'. Reinstall SWX or what? (Repair function doesn't work either...)
