The following is how I 'fixed' the issue at a few schools I support.
The issue is when you are trying to drag items across the smartboard using your fingers it either scrolls the page up or down in the internet browser or doesn't move at all in third party software.
To resolve this you need to turn off the Touch Panning in Windows 7 either:
locally through the Control Panel, or
through Group Policy in a domain:
Workstation / computer settings - edit this policy
Computer Configuration - Administrative Templates - Windows Components - Tablet PC - Touch Input
Turn Off Touch Panning
Hope that helps.
