This results in a noticeable delay when using wxGTK via a remote X11 connection for every key event as a round trip to server is needed to get the mouse pointer position every time a key is pressed or released. Only provide the position on demand. And explain that it's actually not very useful as it's simply the same as the current mouse position.
