KF HD text to speech acting up since update.

[Laserone]

I sent this to amazon (below). Is anyone else experiencing this problem?

Ever since I recently updated my Kindle Fire HD to version 7.4.6, the Kindle fire hd has not been acting right. I rely heavily on text to speech and it will just randomly stop speaking. And I have to flip back a page and forward a page to get the text to speech to work again. In other documents it will read just one word and then stop and I cannot get text to speech to read this document even after re-sending a new copy to the device. I did not have these problems before the software update. In fact, the document that will only read one word I have had this device read the entire document/book to me previously without any errors at all. I feel helpless because all I did was the normal software update. I hope a less buggy update will be released soon!
