If there is a defined and active CADpad alignment on MUS startup, the following dialog will appear to indicate the current user options:
OK: Uses the previously stored alignment data to create the CADpad.
Disable: Keeps the stored alignment data previously set, but leaves the CADpad Grid and Mouse inactive. To reactivate, select the CADpad and check the Grid and/or Mouse checkbox.
Clear: Clears all alignment information. To use CADpad, a new alignment must be set.
