FWIW... Orca and Avant are Anderson's projects with others being gracious enough to volunteer their time, effort and knowledge to help out. Some have even donated money to help Anderson out. With that said....
a) To "demand" an answer for software that is free, as if it is one's "right to know", is not fair to the author. If you paid for the software, I can understand the "customer" having a right to get answers. Or in the case of free software, if there is a security issue etc. to get an answer. But for a free project that is in the works and evolving... let's be fair. Especially since there is only one person who is working this project who has the answers.
b) As a user you have the choice of using Orca/Avant or not. If you don't like the software in its current form then don't use it. Come back at a later date and see if issues have been fixed. Many browsers out there.
c) Please attempt to research the answer to your quesiton, via the forums, prior to posting it. I suspect if you had, you would have first seen the link posted by Circumlocutus and understood the lack of posted knowledge etc. rather than Circumlocutus having to direct your attention to it. Then no one would take umbrage with anyone else
Finally, Happy New Year to all!
