When I use IE 5.0/Outlook Express I get the message "Explorer caused an invalid page fault in module occache.dll". That also causes me to lose the control-alt-delete function and the pop-up message window will not delete. I have used the IE repair tool and that works until I restart the computer. I have also used the start/run with regsvr32 /i occache.dll and that works only until the next restart. I have also downloaded IE 5.0 twice for reinstallment and that makes no difference. I was going to try IE 6.0 but I understand you cannot use Outlook Express with that and you cannot uninstall? Thank you for your help. Jerry
