MacOS X Stack Name Anomalies

[Rob Cozens]

Hi All,

Simple task turned mystery:

I had a stack named "Contacts.rev", and I wanted the name to be 
"Contacts.itw"; so I opened the stack, changed the name to 
"Contacts.itw" and saved the stack as "Contacts.itw".

Not only did Rev change the stack icon when saving (an issue for 
another day); but Rev says the file, "Contacts.itw", is actually 
"Contacts.itw.rev".  If I ask the Finder to search for "itw.rev", it 
shows me "Contacts.itw".

What gives?  Does OS 10.2 support invisible file name extensions? 
How can I fix this?

TIA,
