Exclusion of Restored SONAR detected file

I have searched the forum and help files but find no exact match for this ‘puzzle’ so far.  I have a software used for programming control devices that compiles source code to HEX files.  During the compile cycle, the SONAR in NIS2009 (12.2.0.7) detects a file and quarantines the file which of course causes my compile to fail. I have manually checked this file several times and it is not a virus or threat of any kind, so I go to the Quarantine section and choose to restore the file.  When NIS2009 asks if I want this to be added to the list of exclusions I have the check box marked to do this; it also informs me that I can edit this list manually.  However, I can not see this file added to any list I can find.  All the Exclusion lists are still in their default states with this file not being listed.  I know the file has been excluded because after this all me compiles run without any problems.  Can anyone tell me where this list is?  I have looked in the Scan Exclusions and Signature Exclusions settings and found nothing new there.
