I have produced an simple example!

http://www.hot.ee/mocambo/test_input_ie.html

Click to input field and press ENTER. It fires Click on Button 1.

1.
How to prevent this ?
Detecting event.keyCode == 13 -> event.returnValue = false doesn't help some times (when I have lots of working event handlers same time), it still fires button.

2.
Where IE stores reference to this button ? Maybe it's possible set NULL to this reference or what if I want fire another button instead first one ?
