Stop dead space when I copy and paste

I have audacity 2.0, in the older version it doesn’t allow dead space where as the new version allows it. How do I stop this because its slowing me down?

what I want it to do is when I copy and paste I want the copied track to be pasted into the end of a track before it was simple copy and paste.

Audacity 2.0 supports clips - separate audio regions on a track.

To paste to the end of a track, after copying the audio and clicking in the track where you want to paste it, press the K key which will move the cursor to the end of the currently-selected track.
