Thanks again for the reply cheers Gavin PS - if anyone is interested in a job at DTS as 'technical guy' I'll possibly be leaving soon and I'm sure the boss here would love to hear from you. -- Kind Regards Gavin Legge Technical Manager DTS Limited phone +64 4914 5946 email gavin(a)dts.net.nz cellphone 021 441 299
