In the past few days my mouse makes a clicking noise like it is a Windows assigned noise. It does it at random times, sometimes when I click, sometimes on its own. I checked the Sounds and Audio Devices in Control Panel. All sounds I checked were not the sound I am hearing. I turned off some of them anyway. But I am sure these sounds are not coming from t here. I also looked at the Mouse settings and couldn't find anything to turn a click noise on or off there. I have XP Pro, Maxthon Browser with Spoofbar plug-in, Zonealarm, SBC Yahoo Antivirus and an annoying clicking noise! Help, please.
