Can't select attributes

I created my model a few weeks ago, and had no problem copying attributes from one entity to another. Then I got a new computer and reinstalled TDM. Now I can’t select my attributes to copy them to another entity. I’ve tried reinstalling and looking at various settings. I also tried copying attributes using the physical model explorer. Any ideas or how I can select the attributes again?



it should work. What happens when you try to copy attributes via Physical Model Explorer from one entity to another?

BTW: did you try to copy PK attribute, PFK attribute or “non-key” attribute?
