EPK IE7 Issue Update
A hotfix from Microsoft for the modal dialog problem that prevented EPK-Suite and other applications from operating properly with Internet Explorer 7 has been incorporated into the latest client controls for EPK-Suite V4.3. You can use this MSI to "push out" the EPK controls centrally using SMS or other distribution techniques. Get the fix from v4.3 Downloads.
This Microsoft hotfix does not fix the problem for client machines running the new Vista OS. We are awaiting a fix from Microsoft for Vista.
