Menu muckup.

[uxli]

I was making some changes in Main Menu and then didn't like what I had done so pushed the Revert button at the bottom right of that menu. However it did not revert to what was present in Menu (the button at left of panel) as in the original install, but to a lot of entries that where not there at install time. Is there a way to revert to the original installed Menu?

And in particular - so that I can install updates - get the Updates button back in that menu? I cannot find it.
