Database window closing

I’ve had a couple of instances where I’ve selected a PDF file to view and as soon as I click on it, the DT window closes. If I select to open the database I’m told it’s already open and I get a choice of Ignore or Open. Usually Open opens the database and all is good. Today this happened and neither option worked. Choosing Open left me with a blank window. My database showed up in Recent but no files showed and I kept getting told it was already in us… Finally I shut everything down and rebooted. Upon opening DT after the reboot I still got the message that the database was in use! Huh? But this time choosing Ignore opened it up. Has anyone else experienced anything like this?

Could you please send the crash logs (~/Library/Logs/CrashReporter and /Library/Logs/CrashReporter) to cgrunenberg - at - In addition, please check the console for any messages related to DEVONthink. Thank you!
