File Transfer to Digsby client

I am using Spark in Windows and another user has Digsby in Windows. When I got to send a file via IM, my session is disonncect and automatically reconnected about 10 seconds later. Needless to say, the transfer is aborted to and will not complete. I can reproduce this behavior on each attempt.

I have Openfire 3.6.4 running on a Linux server with File Transfer enabled and TCP 7777 open on the firewall. Thanks in advance for any help or advice!

I have filed this as SPARK-1100, but it could be hard to investigate, especially if this is a Smack library issue (Spark is based on that).
