Jim: What development platform are you likely to be using? I'm using Madcap Flare since it is a single-source Help development tool. Hence from one set of files, I currently produce a .chm for Windows, and also Word files of the same content where hard copy is required. I'll be creating WebHelp soon, but need to get help.air files working first. We're now developing the main software for the MAC, which is proceeding quite well, but this .air issue is driving me nuts. That said, I've just raised a support ticket with Madcap.
