John, just guessing here, but are you hitting the Forums home button or your browsers page back arrow when your done reading a post? If your using the arrow then you're not clearing the cache. You can also try refreshing your screen after you've read a few posts.

Edit: Cache is the wrong word. I meant that by hitting the arrow will bring you back to the original page you started on. So the system doesn't realize you've read the posts.
I don't even know what you're talking about.
I'll tell you how I do it. It's probably stupid, but it's worked for me for years;
1st----- I open up the alerts list.
2nd-----I Right click & send the ones I want to look at to "Open in a New Tab", up top.
Then once I got a bunch of them lined up top, I open 1 at a time, check them out, make a comment or not, then "X" that tab out, and go to the next one.
I do this until the top is empty, or my eyes can't take any more.
I hope you can understand the above.
