3115cn MFP Multi Page Scanning

Having just upgraded WinXP with clean installation of Win7 & reinstalled the software from the original CD for the Dell 3115cn MFP printer, all seems to be working except for the scanning of multiple pages. Using the Launcher to open the Dell ScanCenter & ensuring that the multiple page option is selected, scanning halts after each page. Has anyone come across this before & can make any suggestions?

I wondered if maybe there was a newer version of the Paperport software (currently Paperport Standard 11.1.0.310) but cannot find anything on the Dell support pages.
