                }
            });
            SimpleBrowser.this.backButton.setSelected(false);

SimpleBrowser.this.backButton.setFont(SimpleBrowserGlobals.FONT);
        }

The moment this particular JButton is created it is created as
"selected", even though I have done "setSelected(false)". It does not
fire unless I click onto it, of course, but it appears as if I did and
that's not good. Is there a way I can fix this?

Thanx

Phil:

You don't need the Runnable inside of the ActionListener to make it run
on the EDT. The ActionListener is running on the EDT.

That I did not know, thanx. Does this also apply to
HyperlinkListener, PopupMenuListener and PropertyChangeListener?

Are you sure it is selected and not just in focus?

I tried

SimpleBrowser.this.backButton.setFocusable(false);

But it still comes "focused", or rather, the JButton looks like you
clicked it even though you haven't yet done so.
