hairyhen said:Hope this isn;t too late, but I found a couple of articles which deals with some of the original questions posted in this thread, and also confirms what I said about 1280x1024 being the 'correct' resolution when using a 1680x1050 monitor.

I'm afraid I can't be of further help to you, other than to say double check the setting on the monitor that deals with aspect ratios e.g my Eizo S2110W has a 'Screen Size' setting that you can switch manually between 'Fullscreen', 'Enlarged', and 'Normal'.
Does anyone know what theme is used by the user in the second link?
