I've tried troubleshooting this "invalid seek offset" error that is occurring in a distributed VFP9 application but without any success. I have an ON ERROR clause that will log error messages and on what PC it came from. The ON ERROR clause is set in the MAIN prg and should be called if an error occurs at any point in runtime I thought. So why would the invalid seek offset pop up... and also, this application runs pretty much 24/7 but 90% of the time this error comes up is at night so is it possible other unrelated VFP apps that are running from the network simultaneously could be part of the issue? Any troubleshooting tips??
