After much troubleshooting I've determined that Snarfer is causing a new browser window or tab (depending on browser settings) to open to my home page exactly every 10 minutes.  It doesn't matter which browser is set as default, they all do the same thing. After starting Snarfer it takes between 1-2 hours before this begins to happen.  I've tried uninstalling/reinstalling Snarfer but the problem persisted. Any help would be greatly appreciated.
