R2G, do you ever open the Quick Links menu and click on Mark Forums
Read? If you do that, the software
will zero out every thread as if you've read everything, then when you click on a title in the right column that you know you haven't read, the software
will take you to the first post in that thread since you clicked Mark Forums
I'm not saying that is the explanation for what you're experiencing, but it's one possibility. I often use the Mark Forums Read shortcut like a reset button - when I go to the Portal after doing so, I'll know that any post with the little box appearing to the left of the title contains new posts since I did so.
There will undoubtedly be some teething pains as we track down the bugs and correct them, but some of what members are reporting aren't bugs at all - they're simply frustrations from not being able to make the site respond in the same way it had previously. I've experienced some of that, myself.
I'm confident, however, that as bugs are located and fixed, and as members grow more familiar with the new skin, the frustrations will begin to dissipate and the user-friendliness of CF will be appreciated. Please be patient.
