Updating from os 10 4 to 10 5
You can download an installer for this release from the Active State web site.
Note that Active State Community Edition binaries are not open source and are covered by an Active State license.
Important If you are using Python from a 64-bit/32-bit Python installer for Mac OS X 10.6 and later, you should only use IDLE or tkinter with an updated third-party Tcl/Tk 8.5 (not 8.6), like Active Tcl 8.5 installed.
If you are using Mac OS X 10.6, do not use IDLE or Tkinter from the Apple-supplied Python 2.6.1 in Mac OS X 10.6.
As of this writing, there are at least two known issues with Tk 8.5.9 that are present in Apple 8.5.9 Tk but fixed in more recent upstream 8.5 releases.
