personal.xls is not designed to be closed, but left open (though hidden).
Perhaps the problem isn't your function but your understanding of
personal.xls. It must be stored in your XLStart folder. Save personal.xls.
Hide it. Close it (hit save to keep it hidden). Close Excel. When you restart
Excel, you should see a blank workbook, but you should also be able to go to
Window--Unhide and see personal.xls...

All you say me, I know, but if I try this, I don't use my function with
all books, if I close the Personal.xls and I open other book, don't do
it anything.

But, I try and later I say you.
