Double-clicking issue

Good morning,

I'm using Directory Opus 8 on Windows 7.

When I double-click on a drive or a folder from the Dopus window pane, this opens up Windows Explorer rather than the appropriate folder opening within Dopus. I already have Explorer Replacement ticked (tried both "replace for all folders" and "replace for all file system folders").

I have searched all preferences, but I can't find a solution. This is probably very basic for you, guys... Could you, please give me a hand? Thanks!

Opus 9.5 or higher is required for Explorer Replacement to work on Windows 7.

Opus 8 is some 6 years old and should not be installed on and is not supported for windows 7. Please upgrade to the current Opus 9 version.

Thanks for your answers!
