I was very discouraged about this issue. But then I realized that I can scan items from my printer, save the item to a file which we did anyway, and then when I enter the item in QB I go to attachments and attach it from my computer files. I'm essentially doing the same things as in the scan manager but in a different sequence. 

Also, its very easy to lose attachments from QB. If you ever have to reload your QB your attachments are no longer attached to the item file. 

Once I realized I could do the same thing a different way I wasn't as frustrated. QB was a bit more convenient though.
