But it is possible to do it with a user filter and our current kernel? I don't have any idea of the issues other than "the beast needs lots of feeding", but I can't see how we can do it with the filter and wouldn't be able to do it in a normal driver. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
