New external drives don't appear until restart (elevated/administrator)

I'm trying to organise the mountain of pen drives, compact flash and SD cards I have.
Since the latest update DO won't recognise a new card unless I close the program fully and then reopen it.
If I close the program (without removing it from memory) it still says it can't see the drive.
I can't help but feel this is something stupid I'm doing.

DO 12.29 Build 8272

Make sure Opus isn’t running elevated. (You’ll see “ADMINISTRATOR” in the main window title if it is.)

Ah. That sorts it. Many thanks.
