I don't use Logitec, so I'm not sure my answer will be of much help. I do use JPI TopSpeed, and did a similar program with processes switching on an I/O interrupt about a year ago. As I recall, it took a little head scratching, but the example in the manual was quite right and once I figured it out it seemed rather obvious. Tom Ruby MSRS002@ECNCDC
