ok. meantime i'll test reverting to 2.7b2 to double check. positive that 
was working as described though which is why installing 2.7rc1 was a 
nasty surprise...

well, under snow leopard the kernel (except for osx server) still runs 
in 32bit mode ofr device driver compatability, but if the machine 
supports it the whole userland is 64bit.

this still doesn't explain the change from 2.7b2 to 2.7rc1 though since 
i was running that happily on the same system with the same osx version...

but it could mean you're going to see a lot of simillar reports when 2.7 
goes gold and more people switch to it on snow leopard. i think people 
will expect the stdlib Tkinter to just work.


> Tk 8.5 is also available in 64-bit mode on OSX 10.6, but that version isn't used by the binary installer because Tk 8.5 isn't available at all on 10.5 (at least not without installing another version of Tk).

yes, remember reading this. it would certainly be a big improvement but 
i am also unable to spend effort on this at this time.
