Adium 1.1.4 and Pandion 2.5

[Kmax82]

Question for any of you that have this connection going on on your network. I have fellow employees who use Pandion on the Windows side and I'm using Adium on the OS X side for XMPP chat. When they try to send files to me they get stuck about 90% of the way over. However, when I use Pandion, it comes through just fine.

Are there any pointers that you can think of that I should check to see why this isn't working?

Thanks!
