Sanne Grinovero commented on ISPN-1418:
---------------------------------------

Dan,
I've discussed this with Shadow on irc; it's possible that the version he's testing is from before the fix was committed.
Shadow, let's continue this discussion on the forum only (too many channels open now).. if you could check the newer versions, then if you still have issues we can open a new issue.
