Ok - that all works fine. But in one case I can't help. There're two blocks: master and detail. When I change a value in detail block and then go to the master block without commiting and try to go to the next record. Then I have my favourite alert again. I can't check the block status in PostBlock trigger because from this trigger it's not possible to commit (restricted procedure). So in which trigger should I check if there are any changes ? And of course it can't be Key-NextBlk when I use a mouse to navigate.
