Solution Directory Graphic Displays as XML

We are runing Solution Manager 4.0.

If I perform the following actions...

- Run transaction SOLUTION_MANAGER.

- Select "Goto Solution Directory" (pencil icon) for a solution.

- Expand the solution structure by clicking on the solution name.

- Select the Systems sub-item or the Servers sub-item.

Instead of seeing any graphics in the Graphic tab, I see XML tags. The XML is formatted using Internet Explorer's default appearance.

Any idea what could be causing this? I downloaded and installed the latest version of Microsoft XML (MSXML 6.0), but this didn't change anything.
