Ah cool! You patch looks much better than mine.

No problem. But I don't read this mailing list on a daily manner.  
Therefore it is a good idea to use a CC for me.. :)

Sure.

It works quite well. There is just one issue which is related to my  
test page. Reading the content of the textarea using the command  
"innerText" does not work with your patch (like it works with IE).  
Please use the example attached below. It shows the content of the  
text area after clicking the button "kick me". Your release shows the  
text that was written with "innerText" and not the text in the text  
area.

This seems to be the reason, why "innerText" is working for reading  
the content of the textarea..

This compatibility stuff is very unpleasant..
