Problem with Lister Layout menus

I have a great many lister layouts defined in Directory Opus.
When I right-click on the desktop to show the lister layouts, then select an entry, the lister will not appear on the desktop. When I choose the same layout from the dopus Settings > Lister Layouts menu the lister appears as expected.
I should also mention that I am using dopus on a remote system via RDP.
Do you have any advice?

Make sure Opus hasn't been launched elevated, as that would block the desktop menu from being able to ask it to open anything.
