[Pythonmac-SIG] Suggest Aqua Tcl/Tk 8.4.11 instead of 8.4.12

[Russell E. Owen]

I produce a cross-platform Python/Tkinter application. The last major 
release ran fine emulated on an intel Mac, but when I produced a recent 
alpha, that one did not.

The new version had serious problems with pointer coordinates (in an 
image viewer that shows the image coords as the mouse moves over the 
image). Moving the window trashed the reported pixel positions.

I tracked this difference down to "upgrading" from Aqua Tcl/Tk 8.4.11 to 
8.4.12. The same software runs fine (under emulation on an intel mac) if 
built with 8.4.11.

I have not seen the problem on my 10.3.9 Mac yet, but I have also not 
looked very hard, so I just don't know if it's there.

In any case, the safest course is for Mac Python/Tkinter users to stick 
to Aqua Tcl/Tk 8.4.11. It is the best release I've seen in years, fixing 
some important long-standing issues on Aqua.

Hoping this saves somebody some trouble...
