Some elements not working in Netscape 4.7x

Hi,

I don´t have too many experience programming with HTML, but 
giving my first steps with it, I´ve found something I would 
like to know about. There are some elements (see the txt file 
with the sample code) that doesn´t work properly or doesn´t 
work at all in Netscape Navigator 4.7x, while they work 
perfectly under IE5. What i would like to know is why this 
happens, because I don´t like to say my site´s visitors to use 
IE5; the same way I don´t like someone to tell me which 
browser to use. So I would apreciate a lot if you can answer 
me.
I think the problem is with last HTML 4 specifications but I´m 
not really sure. 
I´ve mailed Netscape support´s homepage but they haven´t 
answered yet.

Well, that´s all. Thanks for your time.

Here×s the sample code:

The <button> element here, doesn't work in Netscape 4.7x while it works perfectly in Internet Explorer 5.0:

Example 1:
<button name="submit" value="submit" type="submit">&nbsp
 <img src="images/argentina.gif" alt="Submit form">
</button>
<button name="reset" type="reset">Delete</button>

Example 2:
<form action="mailto:marco_canderle@topmail.com.ar" method="post" enctype="text/palin">
  <label for="apellido">Last name: </label><input type="text" id="last" size="25"><br>
  <label for="nombre">First name: </label><input type="text" id="first" size="50"><br>
  <label for="e-mail">E-mail: </label><input type="text" id="e-mail" size="20><br>
  <label>Date of birth: <input type="text" name="date" size="20"></label><br>
  <label for="Country">Country: </label><br>
  <select id="Country" size="1">
   <option value="ARG">Argentina</option>
   <option value="BRA">Barsil</option>
   <option value="PAR">Paraguay</option>
   <option value="CHI">Chile</option>
   <option value="BOL">Bolivia</option>
   <option selected value="URU">Uruguay</option>
  </select><br>
  <button name="submit" value="submit" type="submit" tabindex="2"> 
    Submit form
  </button> 
 <button name="reset" type="reset" tabindex="1">
    Reset form
  </button>
</form>
(Also, I'm not sure if <label> works properly in Netscape)

<textarea> doesn't work in Netscape while works perfectly in IE 5.0:

<TEXTAREA NAME="TextA" ROWS="10" COLS="50"></textarea>
