The larghe help file I'm developing is to be distributed online, in 'Adobe AIR Browser Based Help' using flash, for user who don't have flash there will be a Webhelp version and this will open depending on flash.
Now I've had to test that this works across all browsers, and I've found that WebHelp on Safari 3 (not sure about 4 - not tested yet) doesn't work. I mean it really doesn't work, no TOC, no frame, nothing. Basically a blank page.
I've read there is an issue, though this was in previopus version of RH, I would expect support for something like Safari would be just as important as any other browser.
The only work around I have now is for Safari users, without flash, to use the WebHelp HTML (not DHTML) version, which has its own problems of generating/showing a messed up Index ans Search results feature.
Safari doesn't account for a lot of traffic on our site, but I would still like to give them a usable help file.
