Oops, Calin, it is true - and it is not meant to be.

From ODS 10 onward, actions that change the header attributes of
databases were meant to be accessed only through a SPB (Service
Parameter Block), deprecating the old (and dangerous) situation that
allows any user to do it through "any old DPB". Some of the old
parameters became a bit flaky...but this one is alive and kicking. Oh
dear, oh dear!

Worse still, Firebird 2 and higher (ODS 11 and above) were meant
to make this possible ONLY through a SPB, i.e. the honeymoon was meant
to be over.

But in fact *any user* can still change the write mode through
the old API DPB and, hence, can still put the database into a state
where FW is switched on or off whilst there are active attachments.
Tested with both Fb 1.5.5 and 2.0.4. (Not tested with 2.1.x yet, but I
have that sinking feeling that it might still be slipping beneath the QA
radar....)

But - PLEASE DON'T WRITE APPS THAT DO IT!

I'll grab Alex Peshkov on ICQ later today and ask him to take a
look.

Helen
