I have atttached sections of my system log files below.  Specifically, I found the wireless country code being reset.  The system is creating 'shield windows' and generating screenshots.  Finally there are some entries relating to 'frequent transitions' on the ethernet interface.  I am running the most recent version of Mountain Lion on a new iMac.  Is there any valid reason while these processes should be taking place?

 

Much thanks in advance...
