Hello,

There in lies the problem. With a very slow machine even 500 ms wasn't enough. I was still getting duplicate events. I couldn't reproduce that until I set the interval to 1 ms.

The disable is the first line of code. I moved the logging for the disabled timer to after that line of code.

I even wrapped the loop in a try finally. It still queues up the events.

If the duration of that processing is greater than the timer interval then I can see no solution (if you use binding). Do you really need such a short timer interval (I think the minimum true resolution is about 55ms anyway)?
