How do I specify the menu width to a set size instead of responding to the text within? I have three pages in a secondary menu that are different widths, and it looks really sloppy.

Do you have the menu fixes applied - see the 'New Version & Updating' forum

No, didn't know about the menu fixes. I'll look into that. How often is the theme upgraded? Is there a guideline for how often I should expect to need to upgrade? I hope I don't have to do that very often. (And by not often I mean never. But I suppose that's not realistic. Sigh)
