I've heard stories like this before, but never encountered it myself.
I forgot to mention that it is a good idea to give your submit buttons a
"value" attribute. Regardless of how the form is submitted, you should then
have a value for ['submit'].
Reminding the user that they must do anything other than the simplest things
is usually not a good approach. There will inevitably be users who do not
see/follow your reminder and use the enter button. Give the submit button a
value.
