Command window history?

In AutoCAD the command windows has a history function wich i have also found in DraftSight.

But, when i try to recall the input of relative coordinates (e.g. @100<45) in DraftSight i get the absolute coordinate which was the result of the previus relative input and not my former input string "@100<45".

In AutoCAD i just click the "ArrowUP" key an get the entered string.

Is this a missing feature in DraftSight, a Bug or is there an option where i can change the history handle of the command window?
