I am in parallel but they just post cut and paste you jump through hoops requests. This might explain the hang except I continously reduced render settings to draft quality and low dimensions and still get the render but then it flips into hang mode. Then there is the APPCrash shown above which happened quite at random. I gave Smith Micro all they asked for down to the serial number of my underpants - but I don't hold out much hope of help from previous experience from that source.
