G'day, create a DLL that used a system hook that looks for WM_CHAR, WM_SYSCHAR, and WM_MOUSEMOVE messages to any application. Add a timer so that you can detect the lack of messages and that's it! See the hooks overview in the manual. Note that the code MUST reside in a DLL - not a standard app. Regards, Jeff. -- Jeffrey Smartt, Smartt Designs Pty. Ltd. G.P.O.
