DEVONthink Pro (DTP) is refusing to import multiple files, and importing any data results the application “going grey”, where all import (and other) actions are unavailable and menu options are greyed out.
The application “goes grey” after importing a single file or after attempting to add multiple files via drag and drop. If I am dragging multiple files or folders, DTP will add 1 or 2 files (or a folder and a few files), but will not always display that something has been added.
When dragging a single file into a database, DTP will add it, but only sometimes display the file in the database. After adding a single file, DTP goes grey.
Quitting the app and restarting will allow one or two more files to be added in the ways described above before going grey again.
For troubleshooting, I’ve already done the folling:
Downloaded and installed a fresh copy of DEVONthink Pro
Deleted all the preference files for DEVONthink
I am running Yosemite (10.10.5) and DEVONthink Pro 2.9.17
