    customers are complaining about the spellchecker not working - we must use an alternate product (and soon) if you can not get us an answer
     
     
    go here:
     
    https://security.incident-tracker.com/Submit_Incident.aspx
     
    and try the spellchecker

    you have ValidateRequest listed twice in that pre-processor directive code statement
     
    the two statements otherwise are identical unless the F in false is case sensitive
     
    want to try again?
