	Internet Explorer v6 does not properly repaint the window under certain

		1. You + from a window without vertical scroll bars into a window
			with vertrical scroll bars AND
		2. You scroll down AND
		3. You - back.
	To circumvent this problem, when doing a -, we resize the window smaller
	to force it to have vertical scroll bars, then perform the - operation,
	then scroll the window by 1 pixel to force the menu buttons to reposition
	themeselves, then scroll the window back to where it was, then resize
	the window back to its original size.

	We perform this circumvention regardless of the browser type since it
	has minimal affect.

	Since there is no way to detect whether a window has scroll bars, it is
