When trying to type an email on windows live the font size disappears and I can no longer type anything, also when you click on the font size arrow it lets you type the same letter but when you change to another letter it stops working? And on reply when you try to type it frows the cursor to the subject line.

Hi, try install newest Live Mail version. From here: http://explore.live.com/windows-live-essentials-beta

If your program is already the latest, please download the program from the website. Then remove the corrupt Live Mail and reinstall it.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
