I´m using acad2007 but my friends here at work (who are still on acad2002), are experiencing some problems.
I make my drawings and save in a 2000/2002 format, so they can open the drawings too.
Well, they can open, although commands like copy, paste, block, wblock... does not work!
I´m sure that there isn´t no "lock" in my drawings.
And I´m almost sure that this is not a system variable problem neither, because drawings created on their version are just working fine.
Does anyone have an idea?
