copy and paste

i'm having issue's in jj 5.11 with the copy and paste function, it seems that it will only paste the bars that are immediately viewable in the grid edit screen. why won't it paste everything i've selected to copy?
any help would be appreciated.
thanx.

which thread am i looking for?

I have no clue, but I know JJ OS-related questions are supposed to be in the JJ OS-related forum.
