GUI issue

I logged into Xmage today to find that the window sizing and in game sizing of the GUI is very strange. I have been messing around with the GUI settings but can't seem to get anything to revert to what it used to be for me. Any ideas? I don't think it's just the preferences GUI stuff thats the problem but feel free to show me a screenshot of a reasonable GUI preferences page so I can rule it out.
Thanks for your help. I don't know what changed to cause this.
