Is it possible to have a cell automatically display an "X" when a user clicks
on it e.g. using the onClick in VBA? The user does not want to use the "tick
box" under the forms toolbar. He would like an "X" in a cell when he clicks
on it or even double click. The worksheet will also be protected at the end
so that only certain cells can be added. Is this possible? If yes, how would
I go about it? Any ideas?
