I just tried sending out a mailing.
The progress bar churned happily away until it got to the 42nd record, and then it just suddenly hung.
I left it for a good 5 minutes before sighing and accepting defeat.
It did not send after that.
I will find an alternative way to send the remainder.
Thank you very much,
PS Is there also some way of finding out the order in which sendings are done, so I can determine which 42 were the mailings sent, and so I do not repeat to those parties?
