Sensor not firing ??

I’ve started setting up a basic User Interface for buttons using Social’s FPS Template as a guide from here …

Unfortunately, either I’ve done something stupid like accidently disabling something (entirely possible :eek:), or my Blender install is corrupted. For some odd reason, the “mouse over” sensor in the attached file will not fire. I’ve packaged everything so if anyone can look at this and tell me what I’ve missed, I would appreciate it :slight_smile: … thanks!
