Peter, could you test out your configuration with just Xserver and xterm instead of a full manager? Could you also please run xev, and when the white square appears, click in the box with the various combinations of clicking that you use (e.g. one left click, one right click, one middle click) and post the relevant output? Do let us know the combination of button presses that you use. MAQ.
