I, too, have been looking at this vile little program with a disassembler.
It looks like TaskKeyHooks.dll is used for shutting out Task Manager, setting the window size to full screen, and for disabling all the policy settings and such. I think LockDown.exe is actually responsible for making its own window, however--which means that it should be the place to look for the whole "unmovable/unresizeable window" thing. My problem is I lack sufficient experience with assembler to tell where in the program that activity might be taking place. I've seen some discussion on unmovable windows on the MASM forums but I can't search for similar code(!!) so I'm stuck with the old line-by-line approach at the moment.
I may be way off base here, but as I understand it, you have to specify a window's properties (size, position, _moveability_) at the time you create the window. So, it makes sense that there must be one place that defines these for the original window (looks like DigiP's version takes care of that mostly) and another section for popups (where we are currently concerned because of the nasty quizzes that open in popup windows).
I've noticed that they've also put in code to handle multiple monitors as well. It might be nice if we could get rid of that stuff as well. Not that I can spend all holiday tinkering with LockDown.exe, but if anyone else has some suggestions on where to look for the window code I'll be happy to explore it.
