Apple Mail (MacMail) crashing each time I try to email an invoice from QB

I always hit send on an Invoice, and QB opens up MacMail and sends the email out, as expected. 
Today  I tried this with an invoice I send a client biweekly.  But it didn't work;  instead it crashes Mail ("Mail has quit enexpectedly") and the "Emailing form..." window hangs permanently in QB until I quit it.   
I've ensure I'm online, tried changing my email "from" accounts in QB Prefs, sending to different customers, quitting a restarting both QB and Mail,  clearing up any drafts that were in MacMail; power-cycling the computer itself.  

Any ideas?  

Thank you,
