objectdock problem

a problem that im having with objectdock is with my taskbar. in objectdock configuration, when i uncheck the "Hide the Windows Taskbar" button, my taskbar goes away as expected, but the space where the taskbar was is still present and does not go away. for an example, when I maximize a window, the window will maximize, but the space where the taskbar was is present as if a taskbar is there.
