Recently, all customizations disappeared from Directory Opus. I had no toolbars, no shortcuts.... I have no idea why.
I have managed to restore almost everything using the customize and preferences dialogs, except I cannot get copy/paste in the lister to work. If I right-click on a file and select copy from the context menu, it works. If I right-click on the background and select paste from the context menu, it works. But Ctrl-C and Ctrl-V in the same situation do nothing.
If I bring up the customizer and select the Keys tab, these context items show up in Red. I have included a screenshot.
How do I restore those shortcuts to functionality?
