What am I doing wrong?

[MaggieAnnie]

Any ideas...every time I have hit backspace in a post for editing today it has kicked me back into the previous page, just like if I had hit back on my browser button...and when I hit forward on my browser  my whole post  in progress is gone. 

It is making me all  to have to re-type all my posts 2 or 3 times ...I should jsut leave my bad spelling, sigh.

I am so not techy ...any idea what I am doing wrong..this has never happened before and usually if I accidentally browse away when I browse back my post draft is intact... 

thanks
