While going through the IDE preferences, I see an option under "Files and Memory" that says "Preserve stack creator type". When you mouse over all the other preferences, a help pop-up explains what it does, but not for this one. I first see it listed around version 3.x of the IDE, it isn't in 2.2.x or before (where I spend most of my time).
It is also not selectable on any OS but Mac, so I am assuming it has something to do with that OS, but what? Any clarification would be appreciated, I was unable to find it in the User guide or any other documentation available, nor in any online search I tried.
Thanks!
