Certain windows don't give you the option to maximize, nor will they allow you to dock on right/lef side's of the screen (by dragging to the sides)…BUT if you use WINKEY Left/Right they will dock to the sides! But you still can't maximize these windows with WinKey Up.
Unfortunatelly it won't work for Properties Box's in windows (for example), but it has worked for me in some program's where the options windows (for example) don't have the max/min buttion.
