We haven't seen problems sending in bug reports on 10.6, but we had seen problems sending in bug reports if you are behind a firewall that blocks certain ports. We've changed how this works for the next release. In the meantime, I've written a script that would fix preferences on already-installed versions. You can download a folder of scripts from here: http://nowsoftware.fileburst.com/Downloads/Mac/NowXScripts.zip

After downloading those scripts, run the one titled: "Update Now X Authentication"

Please let us know if this fixes the problem you are seeing. If not, I'd like to dig into this with you so we can track it down.
