Default File Manager

When I first set Opus up, I set it to be the default over windows explorer. This worked the first time I opened a file shortcut but since then only windows explorer opens. I tried looking in the "Settings" "Preferences" for the category "Launching Opus" so I could check it was set to start at start-up and be the default. However I don't have that category available. In fact I only have 10 of the 16 categories that should be available in "Preference" (according to the help guide).

Any ideas?

Those features are unavailable in the Light edition.

Purchased Pro, all good now. Thank you. :thumbsup:
