Sytze, I have had similar problems in the past when using external ActiveX calls from the times or using the comms ports. I suggest that once you are in the timer, the first thing you do is to actually disable it then do the processing and enable it when this process has finished. Really it shouldn't make any difference as VFP will not multithread but I found that it worked and stopped the same type of errors happening. Note that the timer will not call ar regular intervals in "time" but "after" a specific time following the processing finishing.
Also if you have any activeX's present have you remembered to set the Autoyield property to be .F. as this can also screw up the VFP timers.
