You’re not alone, it doesn’t seem to be working for many people, perhaps all using Ubuntu and some windows folks. See for complaints (tirades).

It seems to be working for some windows users, and all users with any operating system from bebo and myspace. So, the problem is in the interface between the software, flash and facebook. I would imagine such a problem is difficult to fix, and my impression of Zygna so far is that they lack the IT capabilities to solve this sort of thing easily, but hopefully I’m wrong. Best advice is to give up either facebook or zygna, at least for now.
