Does anyone know why the following script doesn't work if I compile it with x64, the Class is always CarbinetWClass or get the information but no change for a while even I move the mouse, but sometime work a little. If I compile it with x86, no problem.... The script is not mine, I download it here , and forget the name of the author..Ah, it's by bo8ster Maybe I need to ask this question in his original topic...sorry ; =================================================================
