Previous button

Mike,

I was able to open the Dropbox file and it worked pretty much as I expected with the Previous button returning me to the slide I had viewed before the one I was on.  When I clicked the Previous button again it took me to the slide I had viewed before that (as it should).  I unzipped the file you included to hopefully see the .story file but I didn't see that file, just a bunch of .html, .js and .swf files.  I then created my own test file, similar to yours.  I included a button that jumps to a slide not in the correct numerical order (slide 3.2) and then previewed it.  It works exactly the way I expected it to.  I wrote down the slides in the order I viewed them and then used the Previous button.  Each click of the Previous button took me backward through the order in which I had viewed the slides.

I'm not saying there's not a problem, just that I haven't been able to duplicate it.
