Rotate in object mode has stopped working -2.79-

Not sure what I did but the rotate in Object mode has stopped working, there are no object constraints or modifiers, none of the things are locked, and when I try the Rotate tool in a new file it works fine.



In the Rotate tool tab I’ve reset those proportional numbers and type (back to smooth) and even though all that is off it gets reset from 1.0 to the numbers you see there on the screen.

Rotate still works fine in Mesh mode.

manipulate center points only is enabled on the header, next to the pivot

Ah, thank you. I’ve never hit that button before and didn’t even know it existed really.

Cheers.
