I have been getting this error on a report with multiple data sources - why is that though? Should Crystal not be able to do this?
I should also add that this doesn't happen all of the time. It has just happened after creating my preview though...? Was just sat there looking as it should then popped up and wiped my preview. Interesting.
(Apologies for hijacking your post btw!)
