Proxy issue? Online Family not working

My son has a netbook for school, running a school issued Windows 7 Enterprise (32 bit) image.  I had the school (cooperative people!) upgrade my son to a local admin, I installed Online Family and had him downgraded again.  However, nothing is working on this PC despite his account being correctly set up for monitoring.

 

The school uses a regular Windows internet options set proxy server, and the students use Proxy Pal to turn this off for use away from the school network.  Is there any issue with doing this?  The Online Family software was installed and made to work with the proxy manually disabled - before the children were told to use proxy pal - and since Online Family seems to act as an invisible proxy, I was wondering if it was being clobbered by Proxy Pal and if so, can we do anything about this?

 

The school's internet connection (ie the windows proxy when set) is comprehensively filtered, we don't need Online Family to monitor that - though it wouldn't matter if it did - but we do want Online Family to monitor when Proxy Pal has disabled the school proxy.
