COM Objects linger if parameters are passed as a list

[pflaumingo]

When using the ReadExcel.ByRange node if any of the parameters are passed in as a list then COM objects will not get released and linger. For example, passing a list of strings in as the input for the "Range" parameter will cause COM objects to remain active after execution.

Maybe this can be solved by adding every COM object to a new list with a "finally" statement at the end of the code that releases each item in the list?
