I know this has been discussed before but it's still driving me nuts,the way i use SF is to click the todays posts button under quick links,i only click the mouse once but 8 times out of 10 i get the above message,sometimes the only way to get the new posts is to keep clicking the tadays post button and getting the countdown as close to zero as poss.Takes a lot of fun out of the forum for me,anybody got any ideas about this ?

Have you tried View New Posts? Also how are you able to read a topic and then want to see new ones all within 15 seconds? Sounds like you're doing something wrong?
