Support for Windows 7 Cascading Shortcut Menu Handlers?

Will Directory Opus support the cascading shortcut menu handlers introduced in Windows 7 as documented We're using this to work around an issue where 32-bit shell extensions aren't supported in 64-bit windows, and it works with the standard Windows 7 explorer but not DO.

Opus 10 supports these.

I'm running Opus 10 and it's not working for me. I get the root context menu item but none of the cascading children.

Do you have something I could install to try to work out what's not working?
You can PM it to me if you like.
