Can't break blocks with a sword in Creative Modus.

Hello,
I was like that since 1.6 was out in single player gone, then in Creative mode. I picked up a sword and I could not destroy blocks. Summary: If i'm in Creative Mode i can't destroy blocks with a sword. The block just does not break, it's like I'm trying to make when I'm in survival Broke down on bedrock.
