If you have access to your log files, you will most likely get more detail in the sbs.out log file. If you have an IT resource available (or if you are one) then additional information can be learned from the log files.
Does this happen every time you try and create a document in a specific group?
This was the first time it happened. I had to log out and lost my changes (the version didn't save). It's done for now but may be something to look into so I wanted to log it.
