Thanks for the work around idea.  Yours is simpler than the one I came up with.  This is DEFINITELY a QB issue - I have sent my invoices as stated above for years.  When I did my invoicing on May 1, within a day or two of a QB update, the problem occurred.  I tried to contact QB about the issue and have been told that they won't help me unless I purchase a support plan.  I was doing screen share with an agent on another issue and even showed her EXACTly what was happening.  It's not just when you send an invoice, it's when you try to send any email from QB.  I showed her both ways what it is doing.  She told me she would send me an article to fix the issue - she sent me some other article on how to create a template.  It's like these people check their brains at the door - if it is not on their script they are useless.  It is getting to the point where QB is not worth the effort - I'm actively looking for a different product!
