Okay:
It would be easy to say VFP5a may get sick sometimes (I dunno) - VFP6 w/ Visial Studio SP3 is what I use. I don't recall if timer is standard class or OCX with VFP5. When your routine issues a timer.reset, does it set timer.interval to 0 (zero)?

>>Let's see!
>>Your using the VFP6 timer control.
>>
>>1) You have it set to read and write to DBFs at 1 minute intervals.
>>That is 60,000 timer ticks. 1 second is 1000 timer ticks. So assure that your process interval is triggered every 60,000 ticks.
>>
>>2) When the process is triggered, you may want to reset the timer (turn it off), until the process finishes. When the process completes, you could turn it on.
>>
>>So make sure 1 minute = 60,000 and look at possibly using a timer 'reset' when your process is triggered, and let us know how it worked out.
