Ray,

I think that the timer is somehow messing things up. I wrote a short program to toggle the state, compiled it into an existing executable, and ran it directly (not from the VFP command window) from a shortcut on the desktop. It worked just fine. Basically the only difference in what you did and what I did is is the timer, so that's why I say what I said.
