I created a Simuink Library with various subsystems. One day during my editing I somehow cause two of the subsystems in the library to get highlighted and all wires that connect to these blocks (when the library subsystem is dropped into a model) are colored BLUE.
I don't know what I did to make this happen. I also don't know how to interprete what the blue wires or highlighted subsystem means from an execution point of view. Is this changing the meaning of my model in some way?
I'd like to get ride of this... Help?
