I copied Bookshelf 95 files to my XP computer to have
Bookshelf available all the time. On one of the logons
it works fine while another user's logon gives this pop-
up: "There was a problem loading Microsoft Bookshelf.
Make sure that the Bookshelf CD-ROM disc is in the drive"
and the program will not run. Both users are
administrators and have the same shortcut. How do I stop
the program from asking for the disc on the one logon?
Where can I find the problem and how can I fix it?
Please help
