I think it has something to do with the 12.22 update but suddenly I cannot open my libraries with shortcuts anymore by clicking on them, I'm only directed to the ...\Microsoft\Windows\Libraries folder. However when I select a shortcut and choose "open" from the context menu, Windows Explorer do opens the library as normal.
I reinstalled 12.21 and this problem does not occur!
It's still not working in v.12.22.2 beta, but it only happens if I click on a referring shortcut OUTSIDE Opus and in that case I'm directed to the folder Users\Robert\AppData\Roaming\Microsoft\Librairies. Nothing happens after that. When I click INSIDE Opus I'm directed to the corresponding library.
Just found out that if I disable replace Windows Explorer with Opus in the setting panel, the shortcuts open the libraries normally so it must have something to do with the integration into Windows Exporer I suppose
FWIW, I had exactly the same problem w/ 12.2 and have also reinstalled 12.1, which doesn't have the problem. Will watch for an update. Dopus support is the best I've ever seen, so that'll be soon I'm sure. I don't think Leo sleeps.
