Thanks in advance. I have never used DropBox, but answers to the DropBox forum suggest that DropBox has problems with locked files. SQLite relies on file locking for multi-user concurrency. Apparently open MS Office Word and Excel files are affected by the same problem: http://forums.dropbox.com/topic.php?id=18059 To me, this looks like a DropBox problem rather than a SQLite problem.
