Well, that's exactly what I did, via the patch
http://git.sugarlabs.org/dextrose/mainline/commit/ad3897946e013f1ff4020aeab35375ccb122758b

Herein, while in multi-select, the refresh is inhibited (as already stated
before).
So, as a result, the favorite-status IS updated by clicking the
star/favorite-icon (without needing the refresh).

However, this causes our original issue: the favorite-status is updated
(graphically), only when the mouse is hovered away from the
star/favorite-icon.

I guess, if we could somehow cause the mouse to PROGRAMMATICALLY
hover-away/disappear-momentarily when the star/favorite-icon is clicked, we
could be done.
However, I am not able to find a way to do this via pygtk.


Regards,
Ajay
