Let me take a step back....
I was mistaken 12 minutes ago.
Since I love Action Menu soo much, it was inconceivable that it was not the first tweak installed since evasi0n JB'ing a few weeks ago

I immediately corrected the oversite and tested the copy/paste functionality issues described in the OP.
It was definatley negatively effecting copy popup in my very limited testing.
As usual, looks like Mindi is spot in in her diagnostic virtuosity.....
