DraftSight Basic Commands

Hi All,

I am relatively new to using DraftSight so this might be a basic fix.

Basically I do basic plan drawing to design mezzanine floors, pallet racking layouts etc and each time I open to create or edit a drawing some basic command operations such as the offset, copy etc just do not work using the same mouse operations as I have always/previously done.

Could someone point me in the direction as to why this could be? Any help would be greatly appreciated :)
