Ok... So in trying to figure out this frustrating issue, I have discovered what I thought would stop the issue, really doesn't (pop up boxes, message boxes). I can however close the database and it works fine as long as I leave the attachment field alone.
Here is what I have narrowed things down to:
If I use the quick print icon from the ribbon, it prints the form and all the records
If I use the quick print option from File --> Print, QuickPrint, or Print, the report prints.
So....
New question... is there a way to "release" the form from being held like this?
