Thanks Borislav!

I've already tried that... but it didn't work. The methods you see in the code encapsulates the calls to the DB backend which could be FoxPro, MS-SQL or DB2. The actual DB backend I am using is plain Visual FoxPro.

I've found that if I delete the ZAP command (encapsulated by
go_SQL.cmpA_tmpf14.m_Zap()) and get rid of the records by deleting them(actually this table stores very few records) without packing, it works as expected.

At a first glance it seems like the zap command is disconnecting the grid from its rowsource...or something like that... because the columns remain in the grid (they don't go away). What I really don't understand is why this code works fine when I am debugging it.
