Hello Jason,

thanks for your answer. Actually I am shure that this problem is not relating to MM because a plain Tableupdate() also causes the same error.

...Checking Requery() Returns - they are OK.

Anyone else an idea ?
I am still falling over that problem and I am running out of ideas. I modified my testcode a bit (see below) and CURVAL() == OLDVAL() for all fields! (The messagebox never appears)

But I still get the Tableupdate() = .F. with error 1585.
Is there any known VFP issue with locking probs in Private datasessions ?
I am using the same view in about 5 Data sessions.

Still looking for all ideas

Marcus
