I'm new to Java, so I could be wrong about this - have a think about it
though.
If ayone can confirm what I'm saying, I'd like to know.

With C++Builder, the main() thread is the one that handles all the
screen updates,
processing repaint messages etc. when it is idle. If a second thread
changes 
something that causes a visible change, this change only gets repainted
once the 
main thread is idle. I found this out the hard way. The secret is to
make sure 
the main() thread is never involved in any lengthy work - always create
other 
threads to do the slow work.

I am guessing that maybe the same is true in Java, in which case you
really want 
a third thread to do your query, leaving the original thread to process
screen
repaints etc. while the second thread does pretty animations.
