Putting windows in 'reserved' screen space

[HyperHacker]

I've written a program which uses the SystemParametersInfo function to reserve some space at the top of the screen (maximized windows won't occupy the area, just as if the taskbar were placed there). However, Windows doesn't want to let me move any windows into this space. When moving a window, the mouse cursor won't even enter it. The only workaround I've found is to place the windows there before the space becomes reserved, but this is still a problem since any time the window moves (including those which update their position every now and then, like the Language Bar), it gets kicked out of the reserved area. Is there any sort of tweak or hack I can use to disable this, so that maximized windows won't fill the reserved areas but normal windows can still be placed in them?
