PB 12.6 and Row change between retrieve and update

Hi Guys

we are on SQL 2012 and PB 12.6 Build 4088

On machines with IDE installed there is no issue

On customers machine the issue:

We have a Datawindow with 2 tables (A and B)

On our MSSQL 2012 DB a trigger on A (on update) update B

If we do dw.update(), updatable fields are just on A table, but if the trigger is enabled we have the error:

Row change between retrieve and update

This happens just on PB 12.6 Build 4088 and just on machines without ide installed

With our previous version (PB11.1) no issue

We already tried to delivery our pb.ini and pbodb126.ini but no way

someone has an hint?

thanks in advance

Regards
