Move existing tempo track events 4 measures right.

[Ray Yates]

I updated the arrangement adding 4 bars to the length, so I need to move the tempo changes. The slow down at the end of the song is 4 bars early.
Its a complex Rubato ending so I don't want to re-do  it.

I tried using the selection tool then the move tool, but it fails. ( It just removes the selection) I tried Cut and paste, but "Cut" does not work. I tried Cut Special and that worked the first time but then, when I tried to adjust where I pasted it, Cut Special failed after that. 

Both Cut and Cut special now does nothing at all.

Is there a better way?

If you just need to shift the existing tempo changes 4 measures to the right, you can select the section you need to move (using the normal left-click drag, or right-click lasso) and click on one of the tempo change events and drag all of them 4 measures to the right. Hold Ctrl while dragging to constrain vertical movement. Set Snap to 'Measure' to force movement to snap to measures.
