help needed with curses screen control package

[taylor at sdccsu3.UUCP]

	I am having some problems getting the curses screen control 
package to do what I want...and hope someone can offer some help.

	What I want to do is to have the help routine in my program
create its own window, write the help screen to this window, and then
when the user is done reading it remove the window to reveal the original
screen that was 'underneath' (so to speak).
	Using the overwrite (win1, win2) doesn't seem to do the trick!

	Enclosed is a sample program that will give you an idea of what
I am trying to do....if anyone can get this working correctly I would be
most appreciative, as I have been trying all permutations and none have
succeeded.

				Thanks vastly!
