John,

The problem is most likely the comparison with the address: by default, VBA
does case sensitive comparisons, and Address will return $F$5 and your code
has $f$5. At the very top of the code module, before any procedure or
declaration, include

Option Compare Text

Tom:

Thanks for the advice.

The following is exactly what I pasted into the worksheet code sheet:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

If Target.Address = "$f$5" Then
Msg box "Do something "
End If
End Sub

However, nothing happens when I change the contents of F5 and press enter!
When I change
the cell contents, press enter, leave the cell, and then later return and
click on it the
"DO SOMETHING" box activates.

Is this the way its supposed to happen?
