Completely irritated..... HOW do you delete measures/ time??

I know this is a newbie question..... I just can't figure out how to do it.  I'm recording a song for my friend's album.... he originally had a longer first verse.  He decided he wanted to cut the whole verse, begin the song on the second verse.  Pretty easy, right? 
 
So, I delete all the audio and MIDI in the measures he wanted cut.... now, there's about 40-50 seconds of silence and the song begins where he wanted it to begin.  So, how do I get rid of the measures where there used to be music????

I had real difficulty with this for ages because the option for "delete hole" was always greyed out in the dialog and I couldn't work out why. It works for me these days though.

Thanks everyone, I figured it out.  There really should be an easier, more efficient way to do this.  My only major gripe with Sonar!  Well, Staff view.... nevermind.  LOL!
