Hey - just another thought at what may be the hang-up with using CTL+V:

Not sure about P7, - -  but in P6 and earlier,  in order to use CTL+V to paste, sometimes you have to already have values stored in those cells in the Animation Palette (you can't always paste into blank cells).

So, to paste a range from another frame in the Animation Palette, just highlight the target range and hit any of the "store" menu buttons first, then use CTL+V to paste your copied values into that same range.

Sorry, but don't know the rules of why it works sometimes and not others.
