IDLE on OS X - scrolling broken

Hello - I'd like to report a problem on OS X.  The scrolling is
broken.  When you click on the bar (or 'thumb') and drag it up or
down, the bar's movement does not match your mousepointer's movement,
in that with every motion down the bar only seems to respond to about
50% of your movement.  I haven't checked if the horizontal scrolling
has a similar problem.

It's also annoying that using the page down key cannot get you to the
last line of a document, rather only within a page of the last line.
This is not rare among editors, however.  Just annoying.

This is IDLE 2.6.2

I have found that if you run idle from a command line like:
         python -m idlelib.idle
I get error messages that seem to come out every now and then.
For each of the error messages, I seem to lose one character height
of cursor-display connection.  Isuspect this is a Tcl/Tk issue rather
than an Idle issue.

Re: IDLE on OS X - scrolling broken

When I try that I'm not seeing any errors on standard out.  But I
agree that it seems like a problem below the application level.

Upon playing with this more it appears that the problem is much worse
when moving the mousepointer slowly.  Also, it's just as bad when
moving the mouse up as when moving it down.
