Hi Sergey.
All my SCX have following layout
Ist record has SCREEN as UnIQUEid, and blank Timestamp and little else
Next record is Dataenvironment
Next Bunch records are Cursors from DE
Next one seems to be the Form,
and then come all controls

Regards,
gerard

>>I've opened the errorlog on each instance of the error. Its happening on different forms, for instance today it happened 4 times from 6am to 5pm, on 4 different forms. These forms would have been opened a few hundead times during the day but only came up with the error 4 times.
