Mulled this over with my compadre over here and we have some questions/possibilites?
The error log shows a fault during a "mov". It would be very difficult to trace, need to know what brand database and version? When does the Dr. Watson error occur? Does it always occur when users focus on the "telephone number (or whatever)" field?
Or does the error occur upon submit of the form to update the database?
See it could be a problem with the form (perhaps the functions behind it where changed)
MOSTLIKELY: Probably the worst mistake people make is they change the database structure and then wonder why all the forms BREAK. Perhaps they've added a new field to a table in the database and the form isn't quite sync'ed up to it yet???
I'd look for WHAT JUST CHANGED? (database?, network server?) when the errors started occurring?
That's the best we could come up with thus far ???
