When user logs into Excel for first time, Book2 is the first workbook opened
(I don't know why it skips over Book1). When he attempts to create another
workbook by using the CTRL-N command, he gets the error message: "The Macro
'!CheckInstance' cannot be found". If it helps to know, he is only able to
create another workbook by using the New icon on the standard Toolbar. If he
tries by going to File-New... nothing happens.
