Hi Daniel,
              You appear to have discovered an important bug! I don't
we've ever tested abiwidget in a multi-instance environment.
I'm not sure if the bug is in abiwidget or the python bindings. I'll
see if I can find out what is happening.

Thanks very much for the clear bug bug report!

Cheers

Martin
