I've been using BoxCryptor and KeePass together for a while without any issues. I just installed v1.3 and now when KeePass saves changes to its database, I get this error:
"The new file's content does not match the data that KeePass has written, i.e. writing to the file has failed and it might be corrupted now."
The file does appear to be fine. Just in case, I tried to create a new, blank database and I got the same error as soon as it tried to create it on the BoxCryptor drive. I was using KeePass 2.16, but upgraded to 2.18 just in case - same result. I also tried to just save copies of the file to the BoxCryptor drive, and I get the same error, so it's not just when making a change to an existing database. No error if I save elsewhere, including a TrueCrypt container, so this does seem to be an issue with BoxCryptor. I noticed that Dokan is out of the picture with this new version, maybe that has something to do with it? (and yes, I did let it remove Dokan during installation).
