I'm having the same problem. In addition to the office workflow that some have mentioned, I am having trouble as a homeowner. Electricians and technicians are relying on smart devices more and more. When they complete their work, they send the invoice or bill via e-mail. There is no paper copy. This would suit me fine (fewer paper copies to file), except that I am unable to save the invoice because the save button is gray.
Also, why are staff members not monitoring this board? There has been no reply or update since Nov. 25, 2010.
