While that hypothesis may be true, your testing may have been a bit lax. 
You performed the outside-the-monitor test well enough, but with my 
penchant for testing I also performed the following tests:

- Placed another window on top of the one in question

- Turned off the monitor

- Closed my eyes

- Stepped out of the room

In all cases the stack's visible property was unchanged, even when I 
could not see it.

Curious...

But seriously, Mikey, if you're still reading this silly post here's the 
skinny:

the visible property governs whether a stack will be seen when it's 
open, not whether it's open at the moment.  To see if a stack is open 
check the windows:


   if "MyStack" is among the lines of windows() then
