Hi Arnaud, Thanks for your thorough test.

I understand this, but still I believe maybe there can be some performance improvement in the command. I cannot believe that after inserting 400 columns 4D needs near to half a second to do this. >each ctrl+D displays the wheel of death, each time longer than the previous. I >could never bear such waiting time! ->-> 4D appreciates much better duplicate at runtime. In my tests I also saw this happening. Duplicating each listbox in the form editor with 20 columns took longer and longer. I didn't know / expected this to be faster in runtime.
