[IxDA Discuss] Behavior of "Previous" button

[bjminihan at nc.rr.com]

I agree with your point about what tech can deliver.  Web pages 
introduce a quirk here in their asynchronous nature.  Behaviors that 
prevent you from closing a browser to keep you from destroying data 
can annoy and irritate folks, who don't usually have to "confirm" 
anything before closing a browser.  On the other hand, if you 
temporarily save data while the user is working, how do you (reliably) 
detect when they've left the system and want to save what they've 
done, or when they truly want to give up - many folks treat "close my 
browser" the same way they treat a "cancel" button.
