I have attempted to follow the method described in the official documentation assigning hotkeys:
http://www.pixologic.com/docs/index.php/Custom_Hotkeys
I can’t get it to work though. I follow the procedure and I get a message that I have assigned the key. However, when I attempt to use the hotkey, nothing happens or weird stuff happens, like the window moving around by itself or my tool being sculpted without input from me. Believe me, I know it sounds crazy but nevertheless, that is what is happening.
I’m using 4R3 on Mac OS 10.7.3.
