Hood,
Thanks, will check it out but......
Often we overlook the obvious and I may have done just that. In thinking about the problem I was wondering if the computer could be the culprut. Then looking around I noticed that I had the computer, light, router, vacuum, and air cleaner running on the same circuit probably drawing enough to bother the computer but not trip the breaker. Time to see if this is the problem. I got out an extension cord and got a couple of the big draws off the circuit. Ran the 4 programs w/o a problem.
I'm still going to check out the debounce but I thought this info might be useful to you and others. Something to consider in a set up when there are problems.
Thanks for your effort!!!!
Regards,
Jack
