You might want to try to update to the latest version. In the code around where 
you got the divide by zero error it says:
      // make sure that we don't divide by 0 (happens if  display               
                                                    
        // component is not yet on screen                                       
                                                     
        if ((Math.abs(xmul) > 0) && (Math.abs(ymul) > 0)) { ...

So this might be fixed already.
