Now and then, when I click on a worksheet tab to focus it, I get a pop-up dialoque with a Query Builder error:
Text is not a valid, single SELECT statement.
QB-ERROR: NullPointerException
Query Builder disabled.

Please note that I didn't click on the "Query Builder" tab, neither do I want to use the Query Builder at all. I can just close the message and get back to work, but the dialogue is annoying. Is there any way to stop it? Disabling Query Builder would be an option, but I couldn't find anything relevant in Preferences.
I'm using SQL Developer 3.0.04.
