再发问一次，关于iframe的

上次我问过一次了，但没有得到很好的解决方法，这是原贴的地址
http://community.csdn.net/Expert/topic/3468/3468929.xml?temp=.8886377

最近小弟做了个网站，大部分人可以正常浏览，可有小部分人却没办法浏览

我是用框架做的（iframe标签）

请大家看看下面两张图，告诉我为什么会这样，请大家帮我解决一下

正常浏览：http://www.yyfc.com/module/right.jpg

错误浏览：http://www.yyfc.com/module/ldmsapp.jpg

在错误图里面，他出现的是左边的背景图！左边和右边是在同一个表格里，左边是菜单，
右边是一个iframe，请大家帮忙看看！

再附上代码
<table width="778" border="0" cellspacing="0" cellpadding="0">

<td width="193" height="126" align="right" valign="bottom" background="images/membercenter_05.gif"><table width="85%" border="0" cellspacing="0" cellpadding="0">
