I have either the same problem or one closely related. Actually I have two problems. One, when I turn my
tablet completely off, when I restart the tablet, I will receive a message that Mantano is not installed. I will reinstall and everything will be as I left it. This takes relatively little time even with a library of around 1,500 books. Although it is an annoyance, of course.
The second problem is maybe what you are calling the white screen of death. I will open a book and nothing shows, however the progress indicator will always show that I am exactly half way through the book, regardless of where I actually was in the book. I can however hit the back button and get back to Mantano (my library). However when I get back, if I attempt to open another book or the same book, I will get the same blank screen (no text) but with the bottom menu options visable and again the progress indicator showing I am at the 50% position.
I've have found through the fumble around method that the best way to get Mantano responding correctly again is to simply open the app using via the app market. As in I go to the app market and the options are to open or uninstall and chose the open button. At that point everything works properly again.
I don't know what triggers the behavior. It does not happen all the time, but it will happen once a week or so, and both problems appear to happen with either of my tablets: HTC Flyer and Sony S1.
Anybody else experiencing the "Mantano not installed" problem?
