I've been working on a project in blender for a while now, and one day I open my file and suddenly It's not letting me scale or rotate objects using hotkeys. I am able to scale and rotate them in the objects properties panel by editing the values there, but when I press something like "R" on my keyboard to rotate, nothing happens. For some reason, I can still grab objects via the "G" key, but when I try to scale and rotate using keyboard, nothing works. I opened up a new blender window and everything worked fine in there, so I must have activated some weird setting somewhere. Does anyone know how to fix this?
