Summary0005880: Documentation issue with options 'ExecutePreDisk' and 'ExecutePostDisk'
DescriptionOptions 'ExecutePreDisk' and 'ExecutePostDisk' are not entirely clear to me. I have tested them and ExecutePostDisk seems to execute just before the Workbench disappears (just before the game appears), and ExecutePreDisk executes immediately after the game quits (as soon as Workbench appears again).

I understand that ExecutePreDisk and ExecutePostDisk are separate from ExecuteStartup (executes before Splash appears) and ExecuteCleanUp (executes even if the escape key was pressed, and of course after the game ends if loaded). I like all these 4 options, I find them useful. The docs on ExecutePreDisk and ExecutePostDisk are unclear to me however, and their descriptions appear to be reversed from what actually happens. I just find it confusing really. Also, those two options were introduced in version 17.0, and yet I can find no reference to them in the History.txt file or html history. The history docs needs fixing in that respect, and a little more explanation as to what those options actually do would be better. I read them and it leads me to believe that everytime WHDLoad goes back to the OS to load files (like if memory short and screen flashing occurs) that one of those two options will be executed, or when saving games, but it doesn't do that at all. Those two options just work at the beginning and at the end of actual game execution.

Yes, it seems these functions do not work as intended/documented. I'll check this.

I've fixed the behavior.
The functions are now called as intended/documented, before/after switch between OS and installed program.
Please see new beta release https://whdload.de/whdload/whd189.lha
I also added a not to the docs regarding that these commands must not cause any gfx output as intuition base is locked. Otherwise system will hang!
