[Zope] Tiny Tables view problem - win 32

Hello ! i'm trying to use tinyTables with a zope server under win 2k but every time i add a tiny Table, user Anonymous can't see it ! it shows the login box ... and then say i can't access this object ... when using the same method on a linux server, it's working just fine .... any issue ? thx a lot !
