Ahh - i think I see it now.
Is it the middle h2 text that occasionally disappears. This is ie's peeka boo bug and can be cured in a number of ways but perhaps the easiest is the height:1% hack as follows.
Code:
#centercontent {
background:#80FFFF;
margin-left: 149px;
margin-right:149px;
/* border-top:1px solid #000; */
voice-family: "\"}\"";
voice-family: inherit;
margin-left: 151px;
margin-right:151px;
height:1%;
}
html>body #centercontent {
margin-left: 151px;
margin-right:151px;
height:auto;
}
That should cure it for you.
