remove a hole

[Tarkus]

with previous versions was a trivial thing, with 2014 it is becoming difficult. .
Excuse the introduction.
So, I have a sketch with a block where some centers are present.
on some of these centers I make holes, (not on all).
if then I want to remove a hole from a center to do it on another, I go on processing change and from here, with the "centres" button highlighted, I click on the hole center to be deleted by holding down the mausc key, this I always did until 2013, with 2014 , it only works when it wants.
being a block I can't even clear the point from the sketch, even because I need it for other instances.
Is there another way or do I have to get rid of the work to give it back?

It also does to me: usually the point that I can't uncheck is that with the direction symbol of the hole. then deseleziono another hole (this always works to me), rejoin it immediately and the direction symbol of the hole moves to the newly re-selected hole and so I can uncheck what really interests me.
Actually, I go to memory, because this inhibition isn't always there and I can't do a test to see if I just wrote an emeritus st...upidaggine, I got another word :redface:.
Let me know if I got us...
Bye!

I also use your escamotage, but it doesn't always work.
I have several holes in a hydraulic valve lock that I made on points of a block in the sketch so that I have the same mask.
then I decided to change position to some holes:
on seven positions no problem, on one I had to remake the hole.
What I don't understand is why!
