Menu problems Child pages get expanded when you are on top option in menu

[ebismo]

Hi everybody, I'm quiute new to CMSMS and I like it, but I have run into a problem. It used to work nicelly but suddenly all the new child pages I add to the site get expanded when they shouldn't. They only get expanded when you are at the top option of the menu, and not when you go to another page. Also it doesn't happens with some that were created some time ago... weird right?
The structure of my page is like this:

1. Inicio
2. Objetivos
3. Directorio
  3.1 Miembros
  3.2 Consejo
4. Actividades
5. Revista
6. Contacto
7. Fototeca
8. Estatutos
  8.1 Modificaciones
9. Eventos y Convocatorias
  9.1 25 aniversario
  9.2 Convocatoria a asamblea
10. Links

So when you are in the top option (1. Inicio) you shouldn't see any child pages, but you get displayes , but you get displayed both the point 8 and 9 childs, but not hte pint 3 ones that were created before this started happening... if you get to point 2 (Objetivos) everything works as it should, no child pages displayed. I have tried deleting and recreating the pages with childs, the inicio one, changiung the order of the pages. It's all the same, as long as you are in the 1. option you'll get those child pages displayed.

Any ideas??
Look at the site here: http://amtf.amtf.com.mx

Ah, you are using 0.11.2. There was a bug in that version that expanded menuitems under 1, but also under 10, 11,12 etc. Maybe this is the same bug? (maybe not as it appears you have less than 10 top menu items). You might consider upgrading to 0.12. I believe the actual fix was putting one dot in the selection terms, but I don't know where exactly. search the forums, not sure if Ted posted the actual fix or only mentioned it was fixed in svn.

I kept searching and looking for this problem, only to find out you were totally right. I noticed when I was adding a new section that even if I had 9 topics, the numbers were 11 and 12!!! and those were the ones with problems.Probably those stuck to their number after deleting something (there's a minor bug) So yes, its the bug you told me, I'll try upgrading the system.
Thank you very much!!!
