When browsing a .chm file, in search tab, when I click on each result I get a beep. I don't think there should be a beep every time I click on a search result. In any case, I'd like to just disable them.

I know there is a way to disable the beeps system-wide, but I don't require that. It's not the "Start navigation" sound like used in Internet Explorer. This is truly a beep, like the one resulting when the pc is not responding, and one keeps pressing various keys on the keyboard, with each key press generating a beep. Besides, I have the windows "no sounds" scheme, meaning there shouldn't be event driven sounds.
