Right ok.
By mistake I think I managed to open two instances of MFPro of the same profile as I thought I had closed one down. Messed up my triggers I can tell you
I'm guessing that might be the issue.
I've closed all instances, opened the ones I want so now we'll see. There are no conflicting trigger calls (I don't think) so hopefully it won't happen again.
Many thanks for all your assistance everyone
