A DESCRIPTION OF THE PROBLEM :
When pressing enter inside the TextField the windows warn sound occurs. In all previous Java versions no sound occured.

We are running a chat-plattform with 1 million monthly unique users. We use an awt TextField to allow copy/paste without any warnings. Now, everytime a chat message is entered a warn sound is played, which severly limits the usability of our service.

1) go to http://www.knuddels.de/index.html?c=0 and press enter in any of the applet Textfields

OR

2) see attached code
