Publisher 2007 "checks the story" on every email address in a mail merge

When I have finished the document and attempt to send the email, I get the message "Publisher has finished checking this story. Do you want it to check the rest of your publication?" This must be responded to before it will proceed to the next email address and it appears for every individual email. It is impossible to check no or yes for each of the hundreds of emails. :cry

Why is this happening? I have done several mail merges using Publisher 2007 and this is the first time I have run into this problem.

Thank you in advance for your help.
