The screenshots page is updated. Some users have told me that they experienced socket problems with version 1.5. For me it seems to work fine. I'll try to find the bug and fix it. But, right now, I am short on time.
Beta is now on the downloads page.
I haven't tested AOL 4 and proxy support. I would appreciate if people could test these out and get back to me. As for the BeOS version, I'm not sure if I will have time to update it with proxy support anytime soon. Your support is greatly appreciated. I'll release it later today or tomorrow for beta testing.
