I would just take some time every day, tie her up and leave her to figure out that pawing and being all shifty is not going to get her untied.
If you have a safe place to do so, that is what I would do...tie her up, and go read a book within sight distance. It is a good idea to do some hard work before tying her too, that way she is tired and will want to stand...and if she doesn't she should 'tire out' a bit quicker, and stand nicely, than if you were to just tie her fresh out of the pasture.
My horses spend alot of time tied, not just for grooming, and saddling, untacking, etc...tying to me, is one of those ground work exercises that just needs to be done; so tie her up and go about your business, and ignore all the antics; she will figure it out eventually that being tied is a part of the 'normal routine', and won't care when it happens.
