Cubase 6 - behavior of Audio-Part-Editor bug or feature?

Yeah! That is why even if I bought Cubase6 I still go on working on 5, and I absolutely wasted my money on 6.
It is IMPOSSIBLE to recreate some fundamental tecniques based on the old behavior.
That way (the old way) was very “acrobatic”, specially with “bad” singers (but with good money, I do it as professional producer). Everything is simpler for dummies now. You touch it, you active it. But became VERY BAD to use it in a professional way. If you work on 20-30 or mostly more parts together you get mad. What is this for? Looks like a Sounblaster app for the Iphone… I never wanted to leave Cubase till now. If Steinberg will not give me the possibility to switch between old and new mode at least (I mean: if I touch the part, the part DOES NOT turn into ON and I need to MUTE it to hear the upper (not muted) track), I hopefully will die old, but still using cubase 5 (and I’m still quite young) or with another platform, who knows…
