[issue16770] Selection in IDLE often skips first character

Thanks for the additional information.  I am now able to reproduce the behavior you observe when using ActiveTcl 8.5.11.1 and also when using the Apple-supplied 8.5.9 in OS X 10.8; presumably, it is also an issue with earlier versions of Cocoa Tk 8.5.  The good news is that the behavior is no longer observable with ActiveTcl 8.5.12.x and 8.5.13.  I haven't tried to track down what Tk change(s) are responsible.  If you do upgrade your version of Tcl/Tk, avoid 8.5.12.x as there were some serious regressions with it. One of those regressions (Issue15853) remains in 8.5.13 and has been worked around by a change in IDLE.  Until that change is released in Python 3.3.1, 3.2.4, and 2.7.4, you can install a patch for it in 2.7.3.  See http://www.python.org/download/mac/tcltk/ for more details.
