It could be that she has a slightly sore back and when you get on her from the ground it hurts a bit and if you get on from a mounting block you don't have to put as much weight in the stirrup for as long to get on so it doesn't hurt.
I'm not saying you've done anything to hurt her, she may have just done something in the paddock. :)
I am helping to break a mare that has a simliar problem at the moment except her back problem was a lot worse and now even when it doesn't hurt her she remembers the pain and won't stand still.
You might want to get a horse chiropractor out or even a vet to check her over just in case.
Riding a horse is not a gentle hobby, to be picked up and laid down like a game of solitaire. It is a grand passion. It seizes a person whole and, once it has done so, he will have to accept that his life will be radically changed.
