Pardon me for jumping in--But...

do both forms use default data session?
do both forms have their BufferMode property set to 0?
does either form inadvertantly have a data environment that might be conflicting?

...The difference must be in the forms. Have you put a watchpoint when you do a table update in Form B to check cursorsetprop('buffer'...?

>>>I have a tablerevert in the same cmdbutton that works in form A but not in Form B. I append a record in form A and the tablerevert removes the record nut in form B it remains! C:(
