[TYPO3] Why doesn't it stay with the same language?

[Kerstin]

Hi,

Just a couple of things still wrong with my 4-language site.

All alternate language pages show nicely.  However, when I am, say, on a 
Spanish page and I want to go to another page, I click on the page title in 
the menu (yes, that is also nicely in Spanish), it doesn't stay in Spanish, 
but goes to that page in the default language!
Then I have to click on the Spanish flag to get the Spanish page.

Strrrange.

Any suggestions?

Thanks.

Kerstin
