I'm not sure when this started, but when I right-click on a file or folder, the mouse icon turns into a circle as if it were loading. This sometimes takes a long time, and even makes the DO unusable, so I have to terminate the process.
Start with the thing I linked to right above your post. That shows how to isolate the problem to a particular component. (It's very rarely something in Opus itself when the problem only happens when right-clicking files. Almost always a shell extension something else has installed or updated.)
I have already provided that in the link above. Why not try the advice instead of questioning it?
