Hi Gary - thanks for the kind words (and thanks for the stats module
as well, which I've been using intermittently for years).

There is a bug in the _tkagg extension in the python2.2 build which
has never been tracked down and fixed, which is why we stopped
releasing it.  You get a missing DLL error when you try and load it.
I opened _tkagg.pyd in dependency walker, and the DLL is one of the
Visual Studio .NET dlls - though sometimes dependency walker fives
false alarms.

As I write this, it occurs to me the problem that arose in 2.2 may
have been coincident in my changing build environments (I don't know
if Todd experienced a similar problem with his numarray builds with
tkagg and python2.2, but I think he may have ...).

The other backends still work fine for python2.2 (GTKAgg, WXAgg,
etc...).  I don't know if you can use these, though, since you
specifically mentioned interactivity in your post.  I'd be happy to
send this build to you if you like (I built it for 0.61.0 yesterday
after your email).

The other options are

 - I can try and build on my old computer where maybe the problem
   doesn't exist and hence tkagg would work

 - I can try and fix the problem!  Clearly the best solution, but I
   don't have any great leads right now.

Are you primarily a numarray or Numeric user?

Cheers,
JDH
