Hi Bob

The problem with setting itraceinterval to 0 is that the timer event will not fire (therefore resetting the interval property) after you close debug.

>What you want to do is make your timers 'trace aware'... Check out the timer in the VFP 6.0 FFC... but, basically, the timer is looking for the debug window... if it finds it the changes its trac interval to a traceinterval property, which you could set to a very high number, or 0 to turn it off.
