copy paste options

In autocad when I select objects using a window or crossing. Then by using CTRL C + CTRL V I can copy objects from one drawing to anotherk, but this option does not work for objects selected using window polygon or crossing polygon option.

Please help.

Try this,

select the objects using the Cross Polygon Option. Then press Ctrl + C, it will ask you the objects again, then simply pres P + Enter (for Previous selection).

Now PRess Ctrl + V where you want to paste them and it works, I just tried it.
