[pygtk] ScrolledWindow & TextView Problem.

[Dominic Salemno]

Thanks Neil,

I will try this out!
But what is of a concern to me is that the method I described is the
commonly accepted solution and as so, is provided within the FAQ. I
can't be the only one having this particular issue. Perhaps it is the
combination of a ScrolledWindow and TextView... Can anyone verify the
problem I describe?

This was both an issue whether I was running Gnome and XFCE. I did not
try it on another platform such as Mac OS X or Windows.

Sincerely, Dominic Salemno.
