I stayed pretty current on the help files ... when Dave released something new, I downloaded it.
I know that I didn't pull down the last few DLL updates (the ones that added the new GUI items ... and then the latest ones that re-did the font engine) because I had locked down on the DLL version that I made "Gem Raider" with.
But, I don't remember him putting out any new helpfiles, because things were changing too quickly to keep up with them. OziDev and I had just started coordinating to put together some wiki-based help content when all the bad stuff hit ... and so that fell apart too.
There had been a lot of help-like things posted to the old forum as well. Dave would add a new feature, or make adjustments to an existing feature, and then put the function parameters and/or value descriptions in the announcement post.
So ... the short answer is: *I* haven't found any newer help file ... but if someone else has one, I'd like to see it too.
