Running IE7 on XP Home Edition. After applying the above security update IE7 failed to start with message: 'File Download Security Warning Name:Navcancl Type: Unknown file type 2.64 kb From: IEFRAME .Dll Removing the update does not correct the problem. Found that reinstalling IE7 fixes it until the Security Update is reapplied. Also disabling Phishing in Internet Explorer fixes it. Anyone else having the same?
