Prompt Page not presenting when selecting Run in Background

[adam_mc]

We are in UAT following a Cognos BI 10.2.2 upgrade to CA 11.0.13.

I have a Report View that a user runs - When they select the Run in Background option they are not presented with the prompt page (or a defined connection prompt selection), but when they run interactively everything run smoothly.  I am experiencing the same issue running the same report as an Administrator.

However, when I select "Classic View" under Delivery Options everything seems to work fine.

Any thoughts would be greatly appreciated.
Thanks in advance,
Adam.
