I've found another problem: Reading the window proc address with 
GetWindowLong won't work for subclassed windows. We need to pass the 
window proc as a parameter to UnmapMsg32ATo32W (and probably also to 
other mapping functions).

Maybe it's even better to use CallWindowProcW instead of SendMessageW.
