First, kudos on fixing the double progress bar bug I've battled this one for ages.
I seem to have three nagging issues with zip handling:
Since the newest version, right-click menu for zip files on desktop with dopus never shows up (works fine on regular desktop).
With Opus as "system default handler for ZIP files" turned OFF, double clicking on Zip files still opens them in the lister, rather than launching the default handler (WinRAR, in my case). Even after 'Activate Opus zip handling' is OFF, double clicking on zip files opens them in the lister.
Is there anyway for zip and rar files (with the RAR plugin) to show up as folders in the tree, yet opened by separate application (WinRar) when double-clicked?
