Hi,

Very sorry for this bug. I did not take into account the case when one
uses 2 or more Query tool windows. If one launches two windows, it
will create two pgsApplication. However, it will use the same
Flex/Bison parser. Actually I can''t do anything about Flex & Bison
not supporting multiple threads.

So the only immediate fix I see is the one provided by Ashesh plus
showing a message box when a script is running saying that a script is
already running (Magnus suggestion). I do not currently have a
development environment up-to-date: Ashesh, could you add the message
box please?

I write down this bug in my TODO list and will try to manage it better
later. Once again, sorry for this bug.

Regards,
Mickael
