Hi Davidx
We would really need you to submit a PMR so that the relevant Application Support team can take a more comprehensive look into what's happening.
There have been a lot of changes in Notes v9 so we would not be able to isolate the fault without a more detailed review into this problem.
We'd also need to know if there were other changes - specifically if Domino Server was upgraded too.
Anyway, please submit a PMR and we can try get a resolution/work-a-round to you asap.
Thanks,
Paul
EMEA Lotus/Domino Support
