Game keeps starting positioned below the dock at the bottom

not game breaking at all but when I start the game part of the wow screen is below the dock. i have to move up the game window so that the game isn’t hidden by the dock. everytime I start the game it is back to the position below the dock again. wow is not remembering where I have it positioned. i am having to adjust its positioning every time. has this happened to anyone else? does anyone have a solution?
