can't import pdf's until I restart DT

there is something strange here (1.7):
I can’t import pdf’s by drag&drop into DT. I can link them (‘Verknuepfen’).

uhmm… I’m sure that it worked yesterday - therefore I restarted DT and tried again -> works!

I even installed the ‘finder import’ into the menuebar - works fine!

So, what was wrong? (it was the same with jpegs)

No idea  ;) If this should happen again, try to delete the preferences (com.devon-technologies.think.plist) and verify that the import of images and PDF documents is activated. In addition, how many images are inside your database? The Personal Edition only accepts a limited number.
