Trouble editing multiple MIDI notes within PRV on Platinum

Hi all,
I must be going crazy.  I'm trying to edit the velocity on multiple MIDI notes in the piano roll view.  I've done this many times before.
 
I click 'select' on the Tools module and highlight a bunch of MIDI notes in the PRV by dragging a rectangle around the desired notes, so they're all highlighted.  I then right click on one of the notes and edit the velocity on that note and hit "ok". 
 
Shouldn't that edit all the highlighted notes?  All it's doing is changing the single note that I've actually edited, but none of the others?
 
Thanks
Russ
 

Thanks Chappel - I did it via the event inspector in the control bar as you outlined above.  I must be losing my mind though - would have sworn I have always been doing it as described above.  FWIW, CW support couldn't confirm whether my original post was a viable solution in earlier versions or not, so not sure.  Either way, I'll just use the control bar going forward.  thanks.
