First, I have to retract my words where I said "you'd have to pay me to try 15.2 again." I'm trying it again and no one has paid me. What can I say, I'm a geek who likes tinkering...
This version of 15.2 that was posted a few posts up is the best one I've tried so far. I read a library PDF and a library ePub book (both with DRM) with only one kicked-me-out-back-to-main-menu instance. That's great, actually, considering that the same thing would happen with version 14.2 - but more often. So, that's better.
Then, I've been reading my own books (ePubs). The reader has frozen twice (requiring re-booting via a paperclip) and has tossed me out to the front page once. The freezing times happened 1) after turning on (it wouldn't) and 2) unlocking after a key-lock press. Funny though, now that I'm typing this - I don't remember that stuff happening in the past two days.
I flashed my PB360 on 30 July (downloaded the .zip file right after Forkosigan's posting of it). So, that little bit of "bad" in the past 4 days isn't that bad (especially when 1/2 of the trouble occurs with library DRM'd books - and had been happening with 14.2).
In other words, I'm gonna keep 15.2 (and now crossing my fingers in case I jinx myself). I LIKE the double-press action to get back to the main menu and I am truly glad to get it back.
I still eagerly await the advent of 15.3 - mainly for better Adobe DRM support but also so I can quit carrying around a paperclip ... just in case.
Oh, and one last thing. My thanks again to all the people who work on/with Global Pocketbook to keep updating, upgrading and fixing the Pocketbook software. This kind of support (and constant upgrading) is one of the best parts about the Pocketbook line.
