This issue has been mentioned tangentially in other threads before, but not directly.
When trying to send a file from Spark to iChat, the transfer stalls and does not complete. After accepting the initial file transfer request on iChat’s end, the file indefinitely sits in the Transfers window “calculating…” the time and never starts. I’m not sure how else to describe it—please let me know if I can gather more information to post.
Sending files from iChat to Spark, however, does work fine.
XMPP server is Openfire 3.6.3. Tried with Spark 2.5.8 as well as 2.6.0 beta 2. iChat is version 4.0.7 (616) on Mac OS X 10.5.6.
Any solutions or developer activity on this?
