Just a thought, but how about testing (field.value.toUpperCase() ==
field.value) from inside validate(form). This would provide feedback
only if the entire password was typed with the caps lock on (which is
more likely what you are really trying to test). You might also write a
check into the server-side password check that toggles the case of all
alpha characters in the pw and possibly allow that password as legal
(just in case the user has caps lock on and uses mixed case in their
true password).
Personally, alot of times I use upper case characters in passwords when
I know that case is significant and this warning would seeminly
discourage this, which locks out 35 characters from the set of
characters users will use in their passwords just to avoid your warning
message.
