I'm running window 8.1 and Windows live mail.  Every now and then while I am typing or using the touch pad, the view font becomes tiny.  I have no idea what causes it and I can find no way to rest the view font to a readable size.  The only way I can see what I am typing is to set the font very large (like 24 or 32 Point).  I then have to reduce it again before I send so the recipient doesn't get enormous text on their screen.  Anyone with a similar problem?  More important, anyone with a solution?
