User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6 I use ActiveWords (www.activewords.com). Usage of this program includes entering text in non-text contexts. Within Windows the "default beep" sound is triggered when typing outside a text entry context. Turning off the sound associated with the "default beep" allows typing outside a text entry context without triggering a sound. However, when typing outside a text entry context while Firebird is the application in focus I am getting a brief gutteral sound (that bears no resemblance to any know Windows sound file). Reproducible: Always Steps to Reproduce: 1. Install ActiveWords PLUS! (http://www.activewords.com/plus_download.html) 2. Open the Windows Sounds Control Panel, select the "sounds" tab, select "Default Beep", set the "Sounds" pulldown menu to "<None>, and click "OK". 3. Open Firebird and click outside a text entry context within a Firebird page. 4. Start typing and the sound will be heard. Actual Results: A sound is heard. Expected Results: When typing outside a text entry context no sound should be heard if the Windows "default beep" is set to null (no associated sound).
Without having installed all that to see, it sounds like you're hearing a sound from the Type Ahead Find feature. Does this also happen in Mozilla (as opposed to Firebird)? If you go to about:config and change the value for accessibility.typeaheadfind to false, does the sound stop occurring?
