I'm just glad I could use it, it's better and less cumbersome (for larger collections) than other apps and is just generally easier to use.

I've narrowed it down to the Kindle Fire not displaying it at all.

Are you planning to add plain url support or is it always going to have to have an ip address? This greatly limits functionality in that I can't use my dynamic dns address for outside of my home. I'm also noticing limited functionality with the Kindle HD Fire.. in that I can't browse and I'm unable to actually view a file.

I'm actually having somewhat of the same problem, except it's on my laptop. Having to force zoom out every page (specifically on dual page scans) is kinda hard and annoying to do. Just in case, here's my info:
