Another thing I just noticed with GUI windows. (Idk if this was the same in v5)

If a GUI control within the window's width or height extends the boundary of the window, you cannot resize the window where it overlaps. (Assuming because your clicking on the control, and not the window boundary)
Even though the control is hidden underneath the borders of the window, it seems to be above the window border.

If a GUI control passes the borders of a window, it should be hidden and not be able to be clicked.
