Every time I try to open a program, Windows Installer opens and tries to
configure scan.  Then I get this msg in a Scan box: "The feature you are
trying to use is on a CD-ROM or other removable disk that is not available.  
Insert the 'Scan' disk and click ok."  I've been printing out pictures and
checking email, then suddenly this starts happening when I try to open those
functions again just a short while later.  Help!
