That is odd indeed, moving from b2 to rc1 shouldn't change anything in that regard. I'll have to look into this, but that will have to wait until next week. > > i guess i'll re-install python 2.7b2 again to double check, but this seems > very odd... > > also, are you then saying that no-one running snow leopard on a 64bit capable > machine is able to use Tkinter anymore if they install the python.org package > for '10.5.. +' osx...? IIRC not in 64-bit mode, the system version of Tcl/Tk 8.4 just isn't available in 64-bit. Luckily you can use 'arch -ppc -i386 python2.7' to start python in 32-bit mode (This won't work with 2.6 BTW). 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). <http://bugs.python.org/issue8798> describes how the stdlib could be patched to try both Tk 8.5 and 8.4, but it is sadly enough too late to get this into 2.7. There is still time to get this into 3.2 though, if someone works on a patch (I won't). Ronald
