There's nothing special about the page. It's just plain straight text, no special formatting, no images, no tables, no nuthin'. That's what's so frustrating about this bug. (And it's possible this error message has nothing to do with the bug, since it will occur a few times before the bug occurs. The only reason I think it's related is because this is the error message that occurs immediately before the bug.)
As for Framework, I don't know what that means!
Nor do I know how to restart Framework, who MrPI is or how to use KUAL (though I suspect that requires jailbreaking, which is beyond my courage level).
<sigh> Would going back to the Home page or putting my Kindle to sleep and waking it back up affect the cache? It doesn't seem to help with the bug, so if going Home or going to sleep clears the cache, then maybe the cache isn't the issue.
Thanks for any help!
