Thanks for reporting this.  The "jump to Genesis" usually happens when you switch from one volume to another, and the new volume doesn't contain the reference you were last on.  For example, if you're browsing Romans 5:8, then jump to a commentary that doesn't have an entry for Romans 5:8, it gets confused, and just jumps to Genesis 1:1.  In the next version we'll try to at least get you as close to Romans 5:8 as possible.

We'd like more information on the crashes, though, if you can get it.  Can you duplicate a series of steps that will cause a crash, or is it random?  If so, please let us know.  Thanks so much!

I've experienced the same problem.  No crash with version 1.0 on firmware 2.0.2, but since upgrading to iPhone firmware 2.1 and Mantis 2.0.0, I've also experience 2 to 3 crashes.  The crashes seem random, but like you, I will also try to look out for a particular trigger sequence.

I am using firmware 2.1 and Mantis 2.0.0.

I frequently get crashes when I first load Mantis; sometimes 2 or 3 in a row.
What happens is the program will briefly appear on the screen, and then it will shut down and I am back at the iPhone home screen.

Once it starts,  it seems to "settle down" and run crash free.

If I do a reset before starting Mantis, I never get a crash.
Maybe it is memory related.
