Of course I didn't want to ask you for spending more time than you do
now. If you feel more confortable reporting on the list, keep doing it!

Let's see if we can hunt this bug...

I checked this and the "only" problem I found is that the ">=" operator
is working exactly as "=" operator. Exportation seems to work properly.
I guess in your case the problem is that it doen't exist records with
AREA = 3. In that case, when you execute the query "AREA >= 3" really is
executing "AREA = 3" so no records are selected and, thus, when
exporting the "selected features" the result is an empty layer. Could
you, please, check this?

The rest of the operators, including "<=" seems to work ok.

I agree with all these suggestions. Thanks.

Best,
