Replied to message indicator?

[kennyd]

The replied to message indicator, you know the little "check mark" that shows you have posted in that thread, does not work with older threads-I guess those started before the last major upgrade, I understand that...but why doesn't it work if I make a recent reply to the older thread?

Example: 2210/2305 Rear PTO broke. - Page 5 - TractorByNet.com does not show the check mark for me?
