I have the same problem, and I'm on a T1 line pretty much all to myself. Don't bother typing up your posts in another program like word. If it has a tendency to lose your text when you hit the back arrow, then just before you hit "submit reply", select all your text with the mouse and hit ctrl-C (copy)... When you go back, if your text is gone, just hit ctrl-V (paste) and re-submit.
