copy paste weirdness
I created a process within a pool, selected the pool and process and copied it. When I paste it, it pastes on top of the original. When I move the pasted process, it drags all the original process elements (not the pool though!) with the newly pasted process (see attached file).
Then sometimes it pastes some of the elements (in this example, some of the sequence flow lines) down below the rest of the pasted object.
This must be a bug.
