Whenever you are playing streaming music from sites, you might be frustrated with constant clicking sounds from IE. This occurs because some of the websites have flash & frame ads which keep refreshing and hence generating the "Start Navigation" sound turned on by default in Windows. You cannot turn this off from IE, but have to switch it off from Control Panel. Go to Control Panel -> Sounds -> Search for Windows Explorer in the Program list, and disable the "Start Navigation" sound. Now you can enjoy a click-free streaming music 🙂
