Thanks a lot angedelamort!
I would have prefered getting both key up and down messages but I guess I have to settle without it. Very strange though, that you only get WM_KEYUP.
The reason it is called softkey is because it is not associated with a certain function (the function is displayed above the key on the screen).

Are you sure you don't get the WM_HOTKEY message (after registering the hotkey)? Or a WM_COMMAND or something?

Seems crazy that you wouldn't get a WM_KEYDOWN for a softkey... did you check the main message loop for any WM_HOTKEY or WM_KEYDOWN/WM_CHAR/WM_COMMAND/WM_NOTIFY messages?
