Corrections:
• Improved the time accurracy when using cursor measurements.
• When two input channels reference the same input module, the user can now save and recall their settings to and from a global file.

Notes:
• Upgrade to version 2.2 requires formatting of the capture drive.
• It is important to archive captures before upgrading because formatting will erase captures on the capture drive.

New Features:
