Thanks Robert. Restoring from a backup is exactly what I've been doing. But it's odd. It's a database I use about once or twice a week (depending on how much wine I've been drinking), and it's failed to open 4 times since then: the saved dates were 26 November, 24 December, 27 December and 5 Jan. I've used it more often, though, and I've decided to save a copy whenever I save the original. And possibly I'll save the original before opening it as well. I agree that the database is corrupt, but what's corrupting it? I haven't had any such corruptions on any other LO documents (famous last words?) or other files. I've had a closer look, and the corrupt files seem to be the last 46 KB (approx) of the original (which are 184 KB). Both LO and Java are 64-bit versions. Is it a good idea to revert to 32-bit versions? I'm not sure how LO decides which Java to use if given the choice; I assume it picks up the same bit-version. Bugzilla doesn't show any obvious connection between 64-bit and database corruption. ----- Peter -- Sent from: http://nabble.documentfoundation.org/Users-f1639498.html -- To unsubscribe e-mail to: users+unsubscribe@global.libreoffice.org Problems? https://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: https://wiki.documentfoundation.org/Netiquette List archive: https://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
