[issue6864] IDLE 2.6.1 locks up on Mac OS 10.6

Here's a status update:

After testing 2.6.3-pre-rc1 with various combinations of Apple and 
ActiveState Tk 8.4 and 8.5 on 10.5 and 10.6, so far I have only seen the 
"new window hang" problem with Apple's Tk 10.5 (10.5.7) as supplied with 
10.6 Snow Leopard.  Although the Apple-supplied 2.6.1 IDLE runs in 64-
bit, the same hang shows up with Apple Tk 8.5.7 in 32-bit mode as well 
(this with a 32-bit 2.6-svn IDLE built on 10.5 in the manner of the 
standard python.org installers except with AS 8.5 Tk installed during 
the build).  Running this last installer on either 10.6 or 10.5 with AS 
8.5.7 installed (32-bit only), I have been unable to reproduce the "new 
window hang".  However, there are some other serious issues that I am 
still investigating.

The good news is that, so far with one exception and with admittedly 
light testing, I have seen no regressions on either 10.6 or 10.5 using 
Tk 8.4 with 2.6 svn: Apple Tk 10.4.19 on 10.6, Apple Tk 10.4.7 on 10.5, 
AS Tk 10.4.19 on either 10.5 or 10.6.  The exception is documented in 
Issue6951 with a supplied patch that should be go into 2.6.3.

Even without the Tk problems, it is also unfortunate for IDLE users that 
the Snow Leopard Python is 2.6.1; a number of problems with IDLE on OSX 
were fixed in 2.6.2.

So, with more work to be done, my recommendation at this point is to 
assume 2.6.3 can be released with an OS X installer dynamically linked 
as in the past with Tk 8.4 (so usable with either the system Tk 8.4 or a 
user-installed AS 8.4) and deployable on 10.3.9 through 10.6 on 32-bit 
Intel and PPC, where applicable.  Pending further investigation and 
resolution, we should say that 2.6.3 does not support Tk 8.5 on OS X - 
period.
