While running dopus I mounted a new volume on the fly. When the volume appears in the pane it doesn't recognize the correct volume label
After closing the lister and starting a new one it figured out the proper label
I've seen this as well, but also in Explorer sometimes. The notifications don't always get sent or recieved, it would seem.
If you have dopus.exe running elevated (the whole process, not just Admin Mode on a single window) then that could block the notifications all the time.
I don't know what you mean by elevated and admin mode I have all that UAC stuff turned off I am Administrator on the box and I never see that stuff
Assuming you're using Opus 11.18, you'll see "ADMINISTRATOR" in uppercase in the main lister titlebars if there is a problem.
(If it says "Administrator" in mixed case, it is OK and just means Admin Mode is in effect.)
