I obviously have a lot of reading to do to be able to get my head around this.
I've also got 4 exceptions showing under the red button which mean nothing to me. the first is DriverCommand Rule:threadexception:ER_Exception,line 411,file drivercommandrule.gs(1).
I'll copy the others for you if you wish which are about worlddrivercommand not being a drivercommand and similar.
I think this is all beyond my pay scale. Perhaps I should stick to flying helicopters.
