Thanks, applied.
I also took the opportunity to tidy up the menus a little and add access keys for accessibility.
One change I made was to make the Edit and Clear menus not have a default option - e.g. instead of a button with a drop-down next to it, they're now a single dropdown button with icon. I think this works better as there are no obvious candidates for the "default" option for those menus. I'm not overly enthusiastic about the look of those buttons though, so if anyone has a better idea how they should be styled, please yelp (CCing Chethana for his input as well)...
