	Why is this a problem? I think this is a great feature.

	I'm sorry, but I don't see this as a problem.  I
	frequently want to close a row or column so it is
	not visible.  If a user thinks they may have accidently
	closed up a few rows, you can select all and set the
	row height to standard.

	Being aware of it is good, but it is not to
	considered a *problem*.

	Sometimes I want to hide certain figures and include
	others without having it visually mess up a printout,
	which is one reason I like being able to set a row
	or column to zero.

	Again, be aware of it, but learn to use it to
	your advantage.
