"My Quarantined Files -> Add -> browse" only shows paths under Desktop

“My Quarantined Files → Add → browse” only shows subtrees under Desktop … Diagnostics returns “The diagnostics utility did not find any problems with your installation” … contrasted with the browse under “New blocked application” which seems to show the entire file system as expected. Running the updater shows this installation is current at rev. 3.0.25.378 … I was able to add the file by bypassing the “browse” GUI via “add → “+” → (typing in the absolute path)” … is it supposed to work that way?

-thanks in advance
