Show fuature dimensions of part when selected?

SW froze (again) and after is unfroze I saw that I randomly click on costing etc, so I cancel that.

Now I notice that when I work in an assembly and want to edit a part, (blue-isch icon), and I click on it, I DONT see the dimensions anymore. Normally I should see my dimensions automaticaly appear. When I click on them I can edit them in a little white box. Like the lenght of extrusion boss, or width of a diameter.

NOW I don't  get the dimensions automatically when selected part, only if I dubble click, and then I have to again double click to edit the dimension, and I need to regenerate (red/green icon) the model to take effect?

What happend, and how do I get it back?

TIA
