My understanding is that the personal.xls is supposed to open at start up
automatically. Don't know why but my doesn't. It's placed in this directory:

c:\Program Files\Microsoft Office\OFFICE11\XLSTART\

So I choose "Tools|Option|General|At start up, open all files in: " and put
the above path into the textbox. Still the same result, personal.xls just
won't be opened at start up.

I wonder what the problem is. Have I changed some setting inadvertently?
