Subject: Re: [Unicon-group] Soft thread changes
Good afternoon Jafar,
As I am able I'll have a look and see if I can add anything of worth for
the implementation. The idea sounds good. At the moment I am still
trying to wrap my head around the differences between Unicon and
ObjectIcon implementation details.
regards
Bruce Rennie
