Context menu not listing winrar commands anymore

Good sirs.

My right click menu is looking rather bare.
I have rebooted, and I checked Explorer...the Winrar commands work there.
But no longer in DOpus.

I reinstalled WinRar, made sure it had shell integration...

I found a checkbox in settings which had RAR unchecked. I turned the checkbox back on.
Still nothing.

Any ideas?

It's easy enough to switch to pop open Explorer when I want to unrar something but...

If you hold the Shift key down when you right-click do they appear?

If so, check that you haven't turned on the Preferences / Miscellaneous / Windows Integration / Hide Windows items on file context menus (shift overrides) option by mistake.

Shift did reenable the menu.
The box was unchecked (off), so I checked it, hit apply, unchecked it, hit apply again, and my context menus work again.

I'm going to blame Movie Subtitle Downloader for screwing things up, if you have a list anywhere of programs that screw up DOpus settings.

Thanks!
