Which versions of DEVONthink and of Mac OS X are you using? The latest ones (2.7.2 and 10.9.1)? Or could you please send the crash logs to our support address? Thanks in advance!
Yes, I am using the latest versions. But, I had the same issues with the previous version (2.5.2 was the last problem-free version I had). Can I post the log here?
I’ve just checked these actions on Mavericks and they’re working as expected. But I’d suggest to open a support ticket, crash logs are way too long for the forum.
