Nick -  

This is a start for my problem but I need a little more.  I recently created
a new excel file and experimented with using a button but quickly gave up and
deleted it.  While creating most of the file, I had no problems.  However,
the pointer becomes a finger when I insert a formula and try to reference a
cell in another sheet and I am unable from clicking on a cell.  I can still
uses the arrow keys to navigate and select a cell but need to remove this
peculiarity.

I have opened the VBE and located the file but saw no 'modulex' to right
click on.  The sheets of the problem file are listed and fid the following
code: "Private Sub Worksheet_SelectionChange(ByVal Target As Range)
End Sub"

Although I have selected and deleted said code and resaved the file, it does
not appear to take (eg. the code is still there when I reopen the file).

Thoughts?
