Internet Explorer Hangs After Installing Citrix Receiver

Posted by William Diaz on March 14, 2012

Since installing the Citrix Receiver on a couple Windows XP workstations (IE7 and IE8), I noticed that sometimes Internet Explorer was getting hung after launching. In all cases, the hang analysis pointed to a dll called IEInterceptor:

Looks like this is installed with the Citrix Receiver:

To work around the problem, the CtxIEInterceptorBHO Class component can be disabled from the Programs > Manage add-ons tab in IE:
I am not sure of its purpose but disabling this add-on does not affect the normal functioning of the Citrix Receiver.

    I am having the same issue but the add-on doesn’t appear in the browser and when using Outlook 2003 it says Word is not recognized as the default editor.
