All gamers need it and you know it #include <Misc.au3> $dll = DllOpen("user32.dll") While 1 Sleep ( 100 ) If _IsPressed("01", $dll) Then MouseUp ("left") Sleep ( 20 ) MouseDown ("left") ContinueLoop EndIf WEnd It works fine but not perfect. Sometimes it doesn't stop clicking after I release left button of my mouse. How can you fix it please?
