Hi,

I'm sure my question was already answered in this group, and I
searched the archive before I've posted this, but there were too
many articles related to this topic.

My question is :

User A opens a query and has 1 record displayed on his screen, the
record stays let's say 1 hour on his screen.
In the meantime user B opens the same record, changes it, posts the
datset and commits the transaction.
The data on the screen of user A remains unchanged, because there
was no refresh done. Then user A changes the same record, posts
the dataset and commits the transaction.
I suppose the record that user B changed will be overwritten ?
In case I'm right, is there a way of avoiding this ?

Many thanks in advance,
Nico Callewaert
