When I press the back button on my browser after reading a thread the browser goes back to the list of threads but it's a few days old! I have to refresh the side to bring it up to date.

I participate in many forums of a similar type to R/C Groups and this is the only place I've seen this problem.

Is it just me?

Works OK for me.

Works fine for me too. Check your browser cache settings. I use auto, but in the past, I've used 'check every time'. Since on high-speed access, auto has refreshed every time..
