Custom Parameter Option
The parameter value is displayed as "Custom" when the operating system registry has
been edited to set the Summit parameter to a value that is not available from the
parameter's drop down list. Selecting Custom from the drop down list has no effect.
Selecting any other value from the drop down list will overwrite the "custom" value in the
registry.
