<Original title: Font size>

I'm using updated Live Mail in WIN 8.1 on a quite new HP Notebook. All too frequently when composing emails I find that if I accidently touch the bars below the keyboard, the font size either increases or shrinks. I can't find any way to correct it. I can't continue with composing the email so I delete it & start all over.

But when I do that, the incorrect font size reappears in the new message.

I'm losing so much time with this problem, It's driving me crazy! Help!

Is it a WindowsLive Mail problem, or an HP problem?
