I have a number of stacks like that. There is a Rev global 
"gREVallowSaveStackRequest" which, if set to false, does not trigger any 
save prompts. This is global though, so it won't prompt you to save any 
other stack either until you (or the IDE) set it back to true. You'd 
have to put scripts into each stack to toggle that global at appropriate 
times, which can involve a lot of event trapping.

Another way is to: put empty into gREVstackStatus["myStackName"]. An 
changed stack has "edited" as a value in that array, and empty if it is 
unedited. If the value is empty, Rev thinks the stack is unchanged and 
won't ask you to save it. This is safer than setting a global because it 
only applies to one stack, but Rev sets this value for almost anything 
you do. After accounting for all the event trapping I'd need to do, I 
stopped trying. Adding all that to several stacks wasn't worth the trouble.

Instead, I just started opening those particular stacks in MetaCard, 
where the behavior you describe is the default, and it leaves me alone 
without my having to do anything special.

It would be a good feature request.
