you really do need to do something about this, it could be dangerous

listening to dvorack's 9th on headphones whilst working I accidently clicked the top right X that closes the program and, not wanting to close I automatically clicked cancel, and was 'deafened' by the almight loud and shrill beep that serves no useful purpose [to the user anyway] which you get in pro+ when you do this; it made me jump; I knocked over my coffee; it is only by good luck i did not do any damage to work/equipment on my desk; my ears hurt

you have no call to be pushing loud audio through the computers audio channel like this, especially when it is of no use and is undocumented; one of these days someone will be taken completely by surprise and have an accident, and you have a duty of care
