Tempo warp problem

Win 7 C5
I have used the warp tool in the project window and it has worked great till now.

The Vocal track is set to linear I want the tempo to follow
when I set the start of the first hit the time line turns brown I drag a bar to the correct position…go to the next place where I want to move a bar the whole time line moves…it isn’t anchoring…no change in the tempo track.
I’ve checked nothing is locked…HELP I got a client waiting

Dont you need to hold down Ctrl or Alt (cant remember) to “anchor” the position?
