Sebastian Mendel a écrit : I understand. Please note that I react to this question as a maintainer of a multi-user installation. Of the hundreds of users executing from the same directory, some will like a distinct query window, some won't, so I cannot please everyone. This is clearly a case where db-based user preferences would be useful. Anyway, we can offer this choice of options: - never - onlyleft - all But now, which one will be the default? :) I would say "all". Note that if a sysadmin uses "never", maybe he won't please all his community of users... This is why I wanted to avoid this choice. A user who does not like the distinct query window would click the SQL tab instead. Marc
