Maybe it’s just me, but there are things I find in OF that just behave weird. Today I was writing up a task in my project and somehow managed to delete 20 minutes worth of work. I think what happened is that my mouse was elsewhere on the screen, and as I typed, my thumb brushed the touchpad selecting something. At this point, all of my keystrokes became interpreted as keyboard commands.
BOOM - it happened fast. First I saw indenting change and then poof. I had this happen before, and I finally found the task under some other location. This time, no such luck.
