Dell Latitude XT Clicking Issues in Firefox & OneNote

With the faulty N-Trig drivers, sometimes clicking inside Firefox, OneNote 2007, and maybe other programs, a left click will act like a drag-and-drop rather than a selection.
 

To fix:

1. Click Start, Run, type regedit, and click ok (acknowledge the Vista UAC prompt if it comes up).
2. In the registry editor, navigate to "Computer\HKEY_CURRENT_USER\Control Panel\Desktop"
3. Locate the DragHeight and DragWidth values in the right hand pane
4. Select the DragHeight value, click the Edit menu, and select Modify (you can double click as well to modify)
5. In the Value Data field, type 4 and click ok. IMPORTANT! You need to do this step even if the registry editor already shows the value as 4!
6. Repeat steps 4 and 5 with the DragWidth field.
7. Logoff or reboot your computer.
