I have some minor problems on my website www.sopadvert.com. I have tried to use:
ob_start(); #at the starting of the script

and

ob_flush();
ob_end_clean(); # at the end of the script

and all seems to work ok. But going to the next page and trying to go back in internet explorer, the CPU goes nuts sometimes at 100%, while IE crashes.
This is the only place where we use ob_start() or ob_flush(). 

What should we do?
