Vuze question

Ok, I already asked this question at the Vuze forum, but haven’t received a response as have many other with questions there. What does it mean when the “OK” under tracker status is red or gray?

It doesn’t say if you mouse over the red or gray button? I don’t have Vuze on this machine here to check, but almost any button you mouse over gives you information.

No, they all said, “This trackers support multiple hash scrapes per request.”
