Hi Neil,

Thanks for the reply.

I'm not sure whats happening, but it's not to do with 'foreground-color' 
set as None. ... I did a lot of testing before I started to introduce 
None for the color.
(According to pygtk reference None is the default value of that property)

I do have a system thats working for me now, .. but I suspect it only 
working because of some bug somewhere.

I totally ignore the foreground-set property, I never set it now, .. it 
seems to do nothing - set or not set

If I want to change the cells color, I put it in 'foreground-color' 
property, else I leave 'foreground-color' at None.

Thats it, .. it all works nicely like that. Ya, .. I know relying on 
undocumented behavior is bad, .. but I needed something that works now.

Cheers
Steve
