Argghh can't pose bones after keyframe set

Sorry folks, having one of those days. This should be simple but it’s driving me nuts

After I set a keyframe, I am unable to pose the bone and it gets locked into place. The bones without a keyframe work fine until a keyframe is set then they freeze.

Can’t figure out what I have on or off that’s causing this.

Thanks for your help

If you’re curious or encounter this yourself. The problem was the cloth modifier. It apparently is the very last thing you should do.
