I have tried twice today to send a message out to different selected users and get an error:

Invalid from e-mail address entered. You must correct it before sending the e-mails

This error is seen when I select my users to send it to -> am taken to the compose message screen -> then try to load an e-mail template. When you click load - the error surfaces.

This was not a problem prior to the 1.1.5 upgrade, so I am inclined to think it is a bug with the 1.1.5 release.
