transform widget locked?

hello - warning: total noob here =:-)

so noobish i feel stoopid asking this question…

im not sure what i did

but now when im trying to move the cam around with the widget

nothing happens -

the litle grabby hand icon comes up

but when i drag the mouse its as if the cam is locked in place

also the widget looks ‘greyed out’

is there a setting that i randomly turned off and on by mistake?

ps some additional info which might or might not be useful

  1. i can move new assets around not older assets ie assets ive added to the map right now
  2. my cam is blue in color not like the other cams which are black
