Cubase 6.5 Project window behaviour changed?

I have noticed a couple of things that don’t work the way they did before I recently upgraded from 6 to 6.5.
For example, if I double click on a midi part in the project window, it no longer opens the key editor for that part and I have to do it via the menu.
Also, I used to double click within the cycle to create a new midi part within the cycle range, that no longer works.
Anyone else noticed this?

Both works here. Check your preferences.

Checked the preferences, not there.
Turns out it does work some of the time, but double click isn’t working like before for me.
I thought at first it was the right button going on my mouse, but the same issue is there on my laptop.
Never happened before this latest update, weird…

You’re not the first:

Yep, you’re right, it’s not just me then…
