Not sure what's going on here, but here's the best I can describe:

• I use Tomboy extensively, for notes, collecting throw-away passwords,etc.
• Once a couple of months ago, a very important note just disappeared. No reference to the title, no deleting, no way of tracking it down---it was just like it had never existed.
• The same thing just happened today. I think the note in question was actually open when I rebooted, so maybe that's related.

Has anyone else encountered something similar?

EDIT: Happened 3 times

Seems to be the last note I have open when shutting down (which is usually the most important) is deleted without a trace.
