Thanks, Peter and Adam. As far as I know, there have been no failures to see the card correctly when starting up by hand. The customer has put the ap in their windows start-up directory and they see failures around 10% of the time. We may have been lucky, of course. (Or unlucky, depending on how you look at it...) Thanks for the suggestions. We may use the wrapper idea if further investigation doesn't turn anything else up.
