C++ MFC applicaiton runs slow on windows 7 but snappy on XP

I have a C++ MFC application (that was written pre 2000), I've compiled it in Visual studio 2012 and runs responsively in Windows XP, although it runs very slow in Windows 7.
For example when trying to open a file using the open file dialog the application takes around 3 seconds to display the dialog and then around 7 seconds to open the file once the file has been selected.
To run it in Windows 7 I do require the C++ redistributable package.

Any thoughts would be great.

C++ MFC application controls will run slow in Windows 7 and windows vista if they are reading or writing to files when file encryption and fingerprint readers are installed on the PC. In my case the problem application was Digital Persona Pro. And the problem dll's were DpFbView.dll & DPClback.dll
