api_UpdateSysResInfo If the Overflow 6 error shows up in a box with the title “api_UpdateSysResInfo”, the problem is most likely located in the frmErrorMine form. Open it in design view. In the form properties, in the Event tab, look for an entry “=api_UpdateSysResInfo” in the on timer event. Remove that entry so the timer event box is blank. Save and close the form.
