In order to accommodate for the difference in how Netscape draws a text area and IE, 
specify the width using CSS by adding the following:

<textarea name="MyField" rows="4" cols="55" wrap="virtual" style="width:480px;"></textarea>
<textarea name="MyField" rows="4" cols="55" wrap="virtual" class="textAreaBox"></textarea>

<input type="text" name="MyField" size="10" style="width:50px;">
<input type="text" name="MyField" size="10" class="textBox">
 
where width is the exact pixel length you want.

Netscape will pay attention to the size attribute, not the style or class
attributes. MSIE will pay attention to the style or class attributes instead of
the size attribute.
