Right on program shortcut

Whenever I right click on a program shortcut in a lister (typically to copy to another directory) Directory Opus hangs and has to be restarted!

Version 64-bit on Windows 8 Pro (and also happens in Windows 7)

A 3rd party shell extension is almost certainly the cause of that.

Have a look at Crash, exit or high CPU usage when right-clicking certain files for how to track it down and tell Opus to ignore the extension.
