Windows Live Issues: When I send a email it is compressed to 1/3 across screen and down-thus border problems or compress issues?

 Have issues once my email is sent, as if someone replies, I go back to delete sent messages or I merely

send the message back to myself in bcc field- they are thus compressed in width across the screen. I type

a message/email across the screen within about 1" of each side, but after sending the person/s receiving

my email message- thus compressed

to about 1/3 of screen width and thus

going downward rather filling the

majority of the screen width.

What or why is this even

happening? Please Help

Me/us correct this as this

occurred after updating from

Windows 7 to Windows 10.

Thanks!
