--- Comment #15 from roger@beardandsandals.co.uk (roger@beardandsandals.co.uk) --- For information. I enventually tracked the hardware fault to bad solder flow in the area of the dvi-d socket. I still stick by my original comments about usability. To me an outcome of a recovery process that will leave 99.9% of end users clueless of how to safely restart their system is not a good outcome from an end user perspective. This is my last word on this topic.
