HP scanner horror story......

I spent over an hour scanning 100 pages of a book, using an HP 4800
scanner and HP "solution center"/scanner utility. FIgured all was
being saved to MY SCANS folder, as the default was set for. After
getting half way through the book , I decided to stop for the day. So
I exited the scanner utility window, and it went back to the main page
of HP Solution Center. There ws no option about s aving the scanned
images, nothin mroe o be done with th scn session, so I exited from HP
Solution Center altogether. I started up the HP document viewer and
went to MY Scans.....there is NOTHING there! No files/images were
saved/created!
I think now that what was happening when I saw the loading bar
progress and complete the scan was actually just a temp file being
created, and when you are finished scanning all pics for the session,
then it actually creates the files in MY Scans folder. Apparently I
didn't let it do that? All that work down the drain....I could just
choke. Where was the warning...if you exit now, your scanned image
files will not be created? THank you, HP!!!!!
