Been there, done that. I posted a new image full screen technique in some Windows API thread, abut ways to copy the desktop. Sorry, I don't save links, but it's somewhere on the forum. Yes, it also had such adjustments to move the title bar up off the screen. I prefer these methods to _FULLSCREEN, too. Nice job on explaining though. That could be placed in the WIKI with _FULLSCREEN as an alternative.
