I have started to use SquirrelSQL for a PostGresSQL database and looks very nice! However I have a major problem and I did not find an answer on the web.

The SQL editor blinks a lot each time I add a new line or I select the SQL text.
With one line of SQL is not a big deal, but if I have 20 lines of SQL it takes 5 seconds to refresh the text box!

My specs:
java version "1.6.0_43"
Java(TM) SE Runtime Environment (build 1.6.0_43-b01-447-11M4203)
Java HotSpot(TM) 64-Bit Server 

SquirrelLSQL Version 3.4.0

I have a mac 64bit retina display.

Do you have any clue what the problem could be?
Thanks in advance,
