[Stridr]

So I got a Kindle Paperwhite 2 to give to my Mom. This is my first purchase of an e-ink reader. (I've only used android phones/tablets before this.)

After I got the Kindle, I spent about 1 1/2 weeks playing with it and sideloading some public domain DRM-free mobi books. I also did a fair amount of "test-driving" it, reading for a number of hours. It all seemed to work well.

Last weekend I gave the Kindle to my Mom and showed her how to use it. I just checked in to see how things are going with it. She has two complaints.
-- She says that when she touches the right side of the screen to turn the page, it won't turn, and she'll have to touch it sometimes 3-4 times before anything happens.
-- She also says that sometimes when she is trying to turn the page by touching the area in the lower right corner the font will suddenly get very small and/or the options menu will pop up even though she is NOT touching the area near the top of the screen.

Anyone experience these issues? I'm wondering if her unit is defective.

Or maybe this is user error? But it's hard for me to see what she could be doing wrong, since touching the screen to turn pages is so easy and straightforward. She is pretty sharp.

On the other hand when I was test-driving it I didn't have an problems. (But maybe something happened since then.)

All suggestions or comments are welcome!
