Can't resize game window

just logged back in after a month or so (got busy) and I can’t resize the game window. There is no way to grab the corners any longer and I can’t double click on the title bar to maximize the window … i don’t run in fullscreen mode … anyone else figure out how to change window size??

edit:
and when I choose a larger ‘window size’ resolution, it keeps the window the same size and compresses the graphics into it … ?

You most likely have a fixed window size. You will have to change to windowed mode or delete the config file you may have used to set a fixed window size for the client.
