My Laptop (HP-520 ,32-bit Win 7) has arduino app installed on it along with the driver.The rest of the application works fine, but it gets stuck and hangs when i try to compile or upload the program to arduino uno board. It works fine on other computers.I have tried re-installing the application (1.0.6) and drivers dozen of times now. The driver validity can be checked from attachment ,if somebody want to see, arduino uno is connected at the moment.
