Konstigt tabellfel!!

Jag har ett väldigt konstig fel bland mina tabeller på min hemsida..
Ibland visas inte hela, men när man uppdaterar så visas allt som vanligt.

Där är ett exempel..

Hoppas denna kod kan hjälpa till lite..

<table border="1" width="98%" style="border-collapse: collapse" bordercolor="#000000">
	<tr>
		<td background="img/main_bg.gif" style="background-repeat: no-repeat;" bgcolor="#1C485E" height="400" valign="top">&nbsp;
		   <div align="center">
			<table width="98%"  border="0" align="center">
			<table border="1" width="97%" bordercolor="#839DAA" bgcolor="#325C74" style="border-collapse: collapse" cellspacing="0" cellpadding="0" class="alpha">
				<tr>
					<td background="img/main_top_bg.jpg">
					<table border="0" width="100%" cellspacing="0" cellpadding="0" height="18">
						<tr>
							<td width="22" style="border-right: 1px solid #839DAA">
							<p align="center">
							<img border="0" src="img/3.gif" width="13" height="13"></td>
							<td width="128">
							<font face="Verdana" color="#839DAA" size="1">&nbsp;» Klotterplank
					</font></td>
							<td>&nbsp;</td>
							<td width="114"><center>h</center></td>
						</tr>
					</table>
