> what is wrong and what's the good practice ?I TOLD you what is wrong. Let’s follow the flow. Every 8 seconds you call listener. It does the following, very quickly: * Fetch the window under the cursor, assuming the cursor is over a window. * Create a Python window object around that window handle * Install a hook to catch button down messages for that specific window * Function exits, the window object is destroyed, and the hook is uninstalled Then you go back to sleep. While you are alseep, there is no hook. The only time you have a hook is the few milliseconds between your HookMessage call and when the function returns. The right answer is to use a package like pyHook to install a global hook. This is exactly what it is for. https://stackoverflow.com/questions/165495/detecting-mouse-clicks-in-windows-using-python <https://stackoverflow.com/questions/165495/detecting-mouse-clicks-in-windows-using-python> — Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc.
