I have no way of testing the culprit on this one, nor is it a big deal but…
I’ve noticed since v.06 that if you “publish” more than 2 or 3 times in a session that the connection to the host fails, requiring either saving the project and re-starting Sparkle and/or, deleting the publishing cache to re-connect to the hosts communication.
Again, not a big deal since the “fix” is quick and simple but thought I’d mention in case someone else has a similar issue.
