[pygtk] Double click on list item goes missing?

[Stephen George]

Hi All,

I've been trying a pyGTK application ( GRAMPS ) which has the ability to 
double click on a list item, and will open a dialog to edit the entry.

All worked well when using:
  -  pygtk-all-in-one-2.22.6.win32-py2.6.msi

however when I used:
  - pygtk-all-in-one-2.24.0.win32-py2.6.msi

The double click does not open the edit dialog?

Is this a known issue with the pyGTK / GTK stack in these versions?

Thanks
Steve
