I just discovered this and now it's going to drive me nuts - there is an upper limit to the vertical height you can drag a "restored" (that is, non-maximized, non-minimized) window to. I want to be able to exceed this limit. Is there a registry setting or something I can change to allow me to do this?
If you're curious why anyone would ever want to do this, consider this situation: I have a pdf that I want to view page-at-a-time, while getting the zoom as high as I can. If I could drag the bottom part of the window to obscure the footer of the page plus some application statusbar elements I don't care about, and then resize the application to the top of my monitor, I could get a little more zoom out of it then even possible when it's maximized.
I realize that in most cases, one could rotate her monitor to avoid this being an issue, but I don't have that luxury: the stand isn't high enough off the ground to support my wide-screen monitor in vertical mode (not to mention that I find it a little disconcerting to look at a wide-screen monitor in vertical layout).
