Thanks, I have tried the CD mounted manuals, but I have a severe reluctance to introducing programs I have no knowledge of into my computer. The first set I bought took the best part of a day to load into my lap top and corrupted it so badly I had to have it sent away to rebuld, the second attempt, again 3 CD's, all looking like they had been used for god knows what before they came to me, they were not even the same make or even in proper cases. In light of that, I decided to write off the cost as I did not trust the vendor.. Ian
