[QC 9.1]

We have had files (usually Function Libraries) disappear from QC. Today, we lost a function library. What happens is that we work on a function library, save it, go home.

The next day all our files are still there in QC, but one of them (in this case, a function library) has reverted to an old version (5 months old!).

Is this a known problem, and if so, is there a fix for it? This problem is so frequent, that we have started to make weekly backups, but even that means a lot of lost work in 7 days...
