[Typo3-shop] shopping basket is empty after login

[Raimund Bau]

Hi List,

I have installed tt_products on one of my typo3 installations. 
Everything works fine, except that each time somebody puts some products 
in the basket and logs in afterwards (FE user), the basket is empty.

Has anyone ever experienced something like that? I would be grateful for 
any hints!

Thanks and have fun

Ray
