I found my problem. There is a interaction between the Last Pass app when it is turned on to work with applications in addition to web sites. I turned this off and the problem went away. I found this on the last pass forum
t's actually an Android bug with TalkBalk and third-party accessibility services. This previously only happened on Samsung devices, and they fixed in recent OS updates, but it now appears that Kindle Fire HDX has the same bug. You can work around it by disabling the LastPass accessibility service, which provides the app fill functionality.
