Hi, Kenny,
tried to replicate what you are reporting. But I wasn't able to replicate the issue.
So please can you give some more details about how exactly you proceeded?
Are you trying to generate a new dataset within an existing project?
(BTW I tried both generating a new dataset as well as generating a new project - everything without a single issue.)
You used the secondary output tab for this, right?
After I did so on the Report Definition Screen I clicked "Print&Save"; the report is shown I closed that window and answered all the other different messages of TMG (if I'm sure to create a new data set and so on) with YES / OK - everything went fine.
Thanks, Vera
