Hi Daudi,
Thanks very much for the info, sounds very promising.
Well only about 20% of the pdf files I try work on the Cybook.
Here are a couple you could try for me if you have the time:

http://www.chameleon.synth.net/files...DSP56303UM.pdf
Both of these just reset the cybook if I try to open them.
Thanks for the interest
Andy
