Hello Vincent,

Found out where the problem came from.

The behaviour of the cCJDBGrid seen in the avi-file is the result of what i call 'ghost-records' - blanc records or records not completely filled-
In very complex data-structures sometimes blanc-records are generated - not sure why - (we checked them in the datadictionary)
The cCJDBGrid is sensible to these records - the same as the dbForm-. The cDbGrid isn't. That's why is was confused.

So if you see records in the cCJDbGrid disappearing and reappearing again - check your data.
