Strange <table> behaviour

Hello all

I'm getting a very strange behaviour with my

, with the first three having their width parameter fixed (to 80, 250 and 228 pixels). In Visual Studio 2005 I see it right, but when I run it locally, or publish to another server, it shows like in the screenshot. The same happens more or less with the height of the bottom frame O.o Here is the code of the top table, if it helps (only the design part, and i've removed some javascripts) Thanks a lot in advance Francisco Ramos marginwidth="0" marginheight="0" style="text-align: center"> height="78"> height="76" bordercolor="#FFFFFF" style="border-collapse: collapse"> onclick="parent.frames['contenidos'].location.href='planes.a spx'" class="cabecera" id="id1" onmouseout="imguc.src='images/logoweb.jpg'" onmouseover="imguc.src='images/libro.gif'">CURSOS onclick="parent.frames['contenidos'].location.href='paginas/ presentacion.aspx'" class="cabecera" id="id2" onmouseout="imguc.src='images/logoweb.jpg'" onmouseover="imguc.src='images/presen.gif'">PRESENTACION onclick="parent.frames['contenidos'].location.href='paginas/ ayuda.aspx'" class="cabecera" id="id3" onmouseout="imguc.src='images/logoweb.jpg'" onmouseover="imguc.src='images/ayuda.gif'">AYUDA id="id4" onmouseout="imguc.src='images/logoweb.jpg'" onmouseover="imguc.src='images/cefont_blancoverde.gif'">CeFo NT onclick="parent.frames['contenidos'].location.href='paginas/ enlaces.aspx'" class="cabecera" id="id5" onmouseout="imguc.src='images/logoweb.jpg'" onmouseover="imguc.src='images/enlaces.gif'">ENLACES onclick="parent.frames['contenidos'].location.href='paginas/ contacto.aspx'" class="cabecera" id="id6" onmouseout="imguc.src='images/logoweb.jpg'" onmouseover="imguc.src='images/contacto.gif'">CONTACTO
