Read and un-read topics

[GasSavers_katman]

I log in and see the green and blue dots. I select a green dot and go in and read the subjects with the stripes. Then I back out to the main page and continue to all the other green dots. Then I refresh the main page and the green dots don't turn blue. I click on the green dot and no stripes on the message icons, which is correct, back out to main page and refresh and still have green dots. What I have to do is click the green dot and go to the drop down menu and select mark this forum read, back out to main page and refresh then the green dot turns blue. What broke in the system?
