Kindle crashes when highlighting or turning pages
I have an older Kindle (purchased around July 2011) and it has a tendency to freeze.
This happens most frequently when I try to highlight text. It just stops there and I have to manually restart--sometimes it will say that it's adding new data on a blank screen and the it will repopulate the whole Kindle with all my titles, collections, etc., reappearing over time. This has started happening when I try to skip pages too quickly also.
Does this happen to anyone else? Any solutions? I'd prefer not to reformat my Kindle.
Note that this happened on a previous Kindle I owned, which I got replaced, but it's happening on this one as well obviously.
