Hello Cetin, your advice really did help
I only had not first line with multilock on, but ?set('multilock') has show .t.
If I remove first line and keep set multilock on in tool/option/data it did not work and
gives old error. That is strange, because cursorsetprop('buffering'>1) is not possible
with set multilock of, looks like bug or feature.
