Running 2.3.2. and OS X 10.7.3 I noticed that importing pdf’s using File>Import or using the Drag and Drop method doesn’t work anymore. The file is not imported. The log only shows “Failed” in the info status.
The only way to import files is using File>Import>Images (with OCR)… which is bizarre as almost all of my pdf’s are PDF+Text anyway. Usually I’m using a workflow in which Scansnap Manager sends the scanned PDF from Fujitsu Scansnap S1500M to DEVONthink. That workflow is flawless.
Yes, all the check boxes in Options>Import are ticked.
