Great, thank you.
I often work with another Creo window opened on second monitor. Say for instance If the selection of the other window cancels out the feature that is in progress in the first window, then that can be pretty painfull again.
To tell it another way, at the current state, working on two monitors, if I don't hit the Ctrl+A with focus on the second window I can rotate, and review the model freely there, while keep on adding stuff to the first window without having to first finish say a sketch.
Sketch can't be finished till it's defined correctly, and sometimes one has to make pretty complicated sketches.
Guess you know where I'm going while saying all of that. I find that kind of automation on the window activation to be just another loss of functionality, in case there won't be a config.pro option to set it back the good old way. 
Hopefully, I'm all wrong, and all I need is to be told how to use the software. *sigh*
