Jacquie, here's one workaround if your computer keep s crashing or losing its connection while you type:
1. Keep some document open as you read ATP. Something like Notepad or MS Word or an Open Office document editor.
2. When you want to post to ATP, type it out FIRST in Notepad or Word.
3. Copy the text that you just typed, into the Clipboard: Ctrl-C).
4. Paste it into ATP (CTRL-V) and immediately hit "Finished".
Even if you lose your connection in-between hitting "CTRL-V" and "Finished", you still have what you typed in Notepad and can try again after logging back into ATP.
(But you probably already know that.)
