Altium Designer space bar doesn't rotate components

Going to make a guess on this one. In the schematic you can simply select a part and hit the spacebar and it rotates. In the PCB editor the part has to be "floating" in order to rotate it, meaning you have to click and hold it (as if to drag) with the mouse, and then hit the spacebar while "holding" it. The same goes for flipping the component (X-Y), etc.
