Administration of Cognos webparts in Sharepoint 2007 / MOSS

Hi all;

Not sure which is the best place to post this so thought I woudl add it here

I have succesfully managed to deploy Cognos webparts into a Sharepoint environment and am able to add and configure most of the webparts.

However I seem to be having a problem with configuring a metrics list webpart once added to the page. Once I click edit preferences on the page and try to select an entry for the metric package it comes back with the following Windows Internet Explorer error and does not respond to opening up the options to select a package:
