Assisting works! (ALT+<--)
CTM / IWT works in the sense, that my toons will go to the npc and interact with it.
But when i use my IWT as set in the key maps, and i am switsching target, i assist my toons (or get my last target) and interact with that.
If i share my target by another way, for example pressing assist or a normal wow makro everything works fine, just my set IWT (ALT+J) does not work propperly ...
I've got the impressions, that i am assissting my toons. I get their target, but they not mine.
