hi all,

Is it possible to develop CoreData and EOF apps on the same machine?
I did a clean install of Tiger and the DevTools followed by WO.
Now I can't get the CoreData Modeler to work in Xcode2.
Everytime i try to add an attribute or relationship to an entity i 
get this (see below):

Anybody else get this? More importantly, anyone know how to fix it?

cheers cornelius
