when usihg hot mail i can type in the e mail address but the curser will not appear in the reply section . any suggestions Thanks to all replies. After switching from Google to Yahoo the problem was solved.

It is possible that cursor is simply invisible. Workaround: use email application like thunderbird

Sounds like a browser problem.
Try reinstalling whatever browser you are using or try using another one.
