How to have a maximum floating window

Hi All

I have DraftSight 26 installed on two computers. On one of them, which is a bit newer, I can have a floating window that I can maximize totally and float above the main menu. ( see image attached ) 

The other only maximises to a certain extend, not above the menu and with command Ctrl+0

I would love to have the option to freely float as described at the top on both laptops, i love to only focus in the drawing and most commands i type anyway. Any ideas how I can make this happen ? Thanks !
