Well, I have figured it out, it seems is a bug, not a bad configuration.
It happens when going from tree to breadcrumb in Debug view:
In Tree Mode everything;s alright:

Now going to breadcrumb mode:

AHA! The buttons asre disabled !
I'm kind of a noob here and haven't found much use for the Debug view tree (or breadcrumb) data, just the buttons. And don't think this is a feature, I think this is a bug.
Here a video of the disabling of the buttons: http://www.youtube.com/watch?v=5c1kglXX9uI
Any experienced one could tell me about the debug view data contents? it seems irrelevant to me right now.
Anyway, here's the solution if anyone else has this problem, took me HOURS of testng in other machines until by accident I discovered the bug.
