WordDocs.compare throw error on failure

Internally in the script extension, the code executed is the Files.Compare method.  A lot of the extension does the heavy lifting of manipulating the word documents in order to cleanly execute Files.Compare.  Files.Compare by default returns a warning message whenever the two files do not match. The script extension uses that default:

  var tempResult = Files.Compare(fullName1, fullName2);

So, the extension will always log a warning.  However, the extensions compare method returns a boolean so that WordDocs.Compare returns true if the files match or false if they do not:

  return tempResult && picEquals; 

What you can do is wrap your code with some if/then logic... something like this (untested):

Sub CompareWordDocs(file1, file2)
      Dim CompareResult
      CompareResult = Call WordDocs.Compare(file1, file2, 2)
      if !CompareResult
           Log.Error("The files are different")
End Sub

I'm not a very good VBScript coder so I'm sure my syntax above needs work but hopefully you get the idea.
