One of my customers had both their SurfCAM and Esprit software crash last night. They wouldn't post code.

Microsoft did an update to hhctrl.ocx last night (04/05/07). I searched Microsoft's support site, and came up with this hotfix.
Fixed both of their CAM systems.

Goto support.microsoft.com
Search for "hhctrl relocated"

The title for the fix is:
"The Realtek HD Audio Control Panel may not start, and you receive an error message when you start the computer: "Illegal System DLL Relocation""

The KB # is 935448.

Hope this helps someone out!
