Problem with floating form elements

http://delta.jero.net/next/register.php

If you look at the 1st and 2nd row of form elements in the 1st fieldset, you see that Test (1st row) is a bit pulled to the top. Same goes for the 2nd fieldset. But in the first fieldset, the row for the password is perfectly aligned.

Any help would be greatly appreciated.

If I took out the margin on the label it worked fine:

label {
display: block;
margin-top: 3px; <--remove
cursor: pointer;
}

Probably because the first set of inputs are just under the legend...

Thanks :)
