suspicious sessions and R/R loops created for a CSS font

Gentlemen, my application does some R/R loops and creates some sessions/main components which I believe it should not. Lately, from a webdesigner, I have got some improvements of the look of my application, which essentially looks like in the html header. The CSS starts with === /*! * Fon

More SharedEC woes: relationships into SEC not saved?!?

Hi there, this is weird. My EOs have some relationships into the SharedEC — of course, one-way without an inverse; I understand that relationships to SEC are all right, only those from it outside are forbidden. (Am I wrong perhaps? If those relationships were set up in the database without SEC,
