Stacks seem to auto-save... sometimes!

[JonathanC at ag.nsw.gov.au]

Hi. I have 3 questions, which I'll put into 3 separate messages. Here's 
the first:

I recently upgraded from v2.1 to v2.1.2 and discovered, to my great 
relief, that the Rev debugger now clears breakpoints when it's supposed to 
and the Variable Watcher displays properly (variable names and values now 
line up).

However, I've noticed a strange, new behaviour. In 2.1, if I opened a 
stack and did absolutely NO editing and then closed it, I got a dialog box 
asking if I wanted to save changes. A bit annoying but I kind of got used 
to it. (If in doubt, I'd click OK.)

Now, however, I'll sometimes open a stack, make some changes, close the 
stack without saving (because, e.g., I only changed the text in a 'Search' 
field), and the stack closes without complaint. Curious, I open the stack 
up again, and the changes are still there. Other times, I'll do the same 
thing (it seems) and I get the old "Do you want to save changes...?" 
dialog.

What gives? Is Rev REALLY auto-saving (like HyperCard)? And, if so, why 
does it only do it sometimes?
