Here's something I came across that has always confused me. Every version of the sdk has had a compiled HTML SDK document which has all the functions in it. On my system at least, it was always blank when I checked out a function in the file. I discovered that in the properties tab of the file (right click it). there is a check box to Unblock it due to it being compiled on another computer and you have a readable document finally. It's only been 3 years before I found this :/
