Enter key wont submit form

I have a regular form with a few text fields and a submit button. When i fill out the form and press the submit button with a mouse then everything works perfectly, but when i try to submit the form by pressing ENTER key… it just reloads the page and doesn’t submit the form.

And that ONLY happens when i’m using IE… in FireFox everything works just fine.

Any ideas why this is happening :hugegrin: ?
