We have several scripts that deal with accessing list boxes / tree views. Over the past few months they have started to cause the systems to beep. (Some were so bad that we unplugged the internal speaker.) The other time they tend to beep is when we are waiting for a dialog box to appear or close. Once in a while, as the tester runs the test and leaves for lunch, the system will beep 2 to 3 time a second. Moving the mouse will stop it (for a while).
