Huh? That’s odd. So what happens when you press the hotkey Q or click at the widget button? Nothing? Is the 3D widget at any point visible? Note that when you click at it then it turns invisible to allow the transform operation without the widget to be visibly in the way.
Hm, then it’s time to ask for your system specifications. I know that some Intel graphics chips can make big trouble. And i think i have heard of vanishing UI elements too. Blender and Bforartists works best with a ATI graphics card or a NVidia graphics card. So what is your system and your operating system?
And could you be so kind to check if the same happens with Blender too?
