Certain K2 blackpearl components, like the K2 Designer for SharePoint and the Notification Designer, require the Internet Explorer Enhanced Security Configuration (IE ESC) to be disabled. The IE ESC restricts rendering the interactive javascript used by the AJAX controls used to give users a Windows-like feel in the designers. This is a known issue and will be fixed in a future update.

To disable the Internet Explorer Enhanced Security configuration, perform the following steps on the K2 Workspace and SharePoint servers:

1. Open Add/Remove Programs by clicking Start > Control Panel > Add or Remove Programs
2. Click Add/Remove Windows Components
3. In the Windows Components dialog, scroll down until you see the Internet Explorer Enhanced Security Configuration component:
   
   
4. Uncheck the checkbox next to the Internet Explorer Enhanced Security Configuration item
5. Click Next, and the wizard will configure the components
6. Once the configuration has been completed, click Finish. You can close the Add or Remove Programs window.
