<tr> with a 1x1 image as a filler on a table with padding of 2 look thicker in netscape but they look ok in IE.

Why are the <tr> with a 1x1 image as a filler on a table with padding
of 2 so thick in netscape but they look ok in IE?

I'm using IE 5 and netscape 7.01

in HTML where the problem is.

<table align='center' width='690' border='0' cellpadding='2'
cellspacing='0' bgcolor='yellow'>



<!--This is the problem-->
<tr>
<td valign='top' height='1'
background='filler-gray.gif'></td>
</tr>
