However when I run under linux, maximizing the editor sometimes causes all the connections to be come disconnected.
They keep their size and shape, but are not in the correct place. It does not happen all the time and, as far as I can tell, never happens under windows.
Has anyone else experienced this problem and does anyone have a fix?

I've managed to fix the problem now.
I'm using my own connection anchor that subclasses AbstractConnectionAnchor.
Originally I was doing this:
public Point getLocation(Point reference) {
Rectangle r = Rectangle.SINGLETON;
r.setBounds(getOwner().getBounds());
Point p = r.getLocation();
p.x += r.width / 2;
return p;
}
But I had a look at the ChopBoxAnchor implementation and changed it to this:
public Point getLocation(Point reference) {
Rectangle r = Rectangle.SINGLETON;
r.setBounds(getOwner().getBounds());
r.translate(-1, -1);
r.resize(1, 1);
getOwner().translateToAbsolute(r);
Point p = r.getLocation();
p.x += r.width / 2;
return p;
}
This works, but I'm not sure why. Shouldn't the original have the same effect?
