I am using NexusDb version 1.08 and it does give me an error when a
record is locked. Unfortunately it does not resolve the conflict by
preventing the second user from editing the record. Which means that
the first user can't exit the record and post because the second user is
still editing the record.
I am guessing that this is a problem that is tied to the Blob Memo that
the user is trying to edit. Since Blob memos are handled differently
than regular records, I am thinking that is why I am getting these ugly
error messages.
What do you suggest?

Hi Thomas,
as usual "it depends".
Which Database do you use? A "normal" SQL Client / Server RDB (as
Firebird or Interbase) is able to handle that automatically.
So, which Delphi version and which DB you are talking about.
Have fun
