Class behaving like a static class

[gu]

Hi to all,
i have a module (a single .py file, actually), with a class called 
HashedDir.

when i import the file and instanciate 2 instances of that class, when i 
check the object's fields they're always the same, even if the two 
objects should be different.

Eg:

h1 = HashedDir('someValue')
print h1.value # someValue
h2 = HashedDir('someOtherValue')
print h1.value # someOtherValue
print h2.value # someOtherValue

Any idea?
Thanks in advance
