Most of the time, my Viewer won't open a book. First open or not. Occasionally it works fine for a whole session of me opening books (to verify name on cover, read, whatever). But then I go for a while and it doesn't work. Opening it just sits there and "spins" (ie loads).
I've done searches here. I know that it might be a cache problem. But I am absolutely clueless about how to do the suggested move of the cache if that's what's needed.
