Hi Barry,
This problem is a known behavior of the IE, the first submit button on the
page will be fired(it is always on focus) when the user hit the enter key.
I think Jason's suggestion that use the client script to capture the
keypress event and cancel it is reasonable. And here is a test page I made
and it worked well. Please refer to it to see whether it works on your side.
