Yes, pretty much stack = window, though stacks can be invisible, or  
have an offscreen location, or be "in use" as libraries and have no  
screen presence at all. Stacks as windows have different modes, which  
determine how or if the user can interact with them. Check out the  
"mode" entry in the LiveCode dictionary.

The saving of the time in a customProp is because I have scripted  
things so the stack is automatically saved every 20 minutes, or at  
whatever interval the user chooses in the preferences. That feature  
was irrelevant to your question and I could have taken it out,  
probably should have to avoid confusing you....
