tabs disappear when using menu.module to add menu links to the tabbed pages

I have three views that are set to be pages and show full nodes of flexinodes. The views themselves work fine. I have them set to do the menu as tabs across the top and that was working fine. I’m doing a lot of re-arranging on this site and at some point the tabs stopped working. The views still show up fine when I go to each URL, but the tabs are gone.

I think, but haven’t been able to confirm, that it has something to do with me adding the views to the main menu. I’m using the nice_menus module and I have a menu item that goes to the base page and three subitems for each view. The reason I suspect there’s some sort of conflict is this:

After giving up on the tabs for the moment, I decided to add titles to each of the pages to make them look better. I added the title to two of the three views and then noticed that my menu had changed by itself. Instead of being set up as I said above, the two views I had made titles for each had its own menu entry and the third was missing. I then added a title to the third view and everything went back to how I had originally set it. So there seems to be some interaction between the views and the main menu.

Unfortunately, disabling the menu items as well as disabling the nice_menus module did not bring back my tabs, so I can’t confirm that they are the problem. I just suspect the problem is somewhere in there and I did notice the tabs were gone after I had changed the main menu.

I’m attaching all three views in case there’s something helpful in there.

Thanks,

Michelle
