Hi,
Is it a GDI+ issue ?
Or JAG datasource changing during preview. i.e. record pointer moved for some reason.
What Version are you running.

>Thanks Neil. We'll give it a go...though I'm not sure why caching of any form should prevent the data appearing on the report - the data should be present in the cache and it shouldn't just disappear. I know ACT! databases have the same problem, and we often aopply the registry hacks to disable oplocks and caching to see what happens (usually not much).
