Rhino 6 Copy & Paste Slower than Rhino 5

Hi all,

It is quite obvious that when you copy and paste in Rhino 6, it is much slower than doing it in Rhino 5.
Sometimes when you copy and paste just one simple curve to another rhino 6 file, it could take one minute (not the case of doing auto-save). And sometimes it could crash…
I wonder why this thing happen and if there is a way to help on this situation?

thanks,

Jack

This is not a generalized case, works fine here and for most people… Can you run SystemInfo in Rhino and paste the results here?
