Why does the contextual menu not work?
When the contextual menu and/or the action menus in DEVONthink don’t work, please check if the file ‘BabylonCMPlugin’ is installed in ‘~/Library/Contextual Menu items’ or ‘/Library/Contextual Menu Items’ (where ~ is your home folder). If it is, try to remove it e.g. by moving it to the trash; then restart your machine. The BabylonCMPlugin seems to be buggy and lead to such side effects.
