I just realized that there is a forum for "Express Invoice for Mac", after I posted my question in the "Express Invoice" forum.
I am wondering if someone has encountered the same problem. I just purchased Express Invoice.
My problem is:
When I make an invoice, I add some items. When I reopen it, all the fields (QTY, Item, Description, Unit Value, Tax, Line Total) are shifted one to the right, and then the subtotal & total become $0.00. So if I want to edit the invoice, I have to start over and add the items again. The preview and print of the invoice and the amount of the total in the invoice list remain the same (thank God!).
I suspect there is a bug in the software causing this problem...? Is there any way to fix this problem or do I have to wait for the next update????
