I'm still getting used to my Kindle-and enjoying it.  However I've noticed something strange.  I set the "reading progress" to show one thing, and in the course of reading, it changes.  I will set it to show time left in chapter and while I'm still reading, it changes to time left in book or turns off the reading progress altogether.  This might make more sense if it happened when I closed and reopened it, but it happens during one single reading session.  Has anyone else noticed this?  Is this a bug or am I doing something to affect it?

Thanks!

Yes, you are accidentally touching or brushing the lower left corner where you can tap it to change it.

Oh-thanks!  I'll be more careful :-)
