I don't know if this issue is actually caused by Direcory Opus, but when I right-click on an image file the context menu appears unusually wide as shown below:
several possibilities
(does not come through dopus!)
the program photos:
has been uninstalled
is not up to date (windows store)
is blocked by firewall/others (wants internet access)
has been changed by other software (context menu)
the normal link has been changed (windows standard apps)
too many entries cleaned (programs to remove garbage)
