I placed the code for a TwentyTen navigation bar in a Kubrick-based theme, and it works fine, but... when I choose to create a custom menu from the dashboard, the nav bar disappears.
The nav bar works fine with the existing page hierarchy set up by setting order numbers in the pages dashboard, and using parent and child pages.
I made sure I had the dashboard menus functions copied over from TwentyTen's function.php page, so that allowed the menu functions to appear in the dashboard of my Kubrick-based theme, but when I chose to activate a custom menu setup I made..... poof, the nav bars disappear.
Any idea what I need to do? I looked in the TwentyTen functions page for more functions but I'm not seeing them.
