 /*

 	Modifications (last one on top):

+		20121014 - WVR: Added second Tracker Source for Arduino solution. The two will be mutually exclusive.

 		20120929 - WVR: Disable button Filter-settings when StartTracker.

 		20120918 - WVR: When AutoStart is TRUE, the program is not directly minimized any more.

 						This now depends on the AutoMinimize time. Fixed the 'not showing' of the MIB.
