In the effort to make myself more clear,
When I am at work, everything works great. I read a thread, hit refresh, and all the little blue unread flags disappear.
I go home, and they all reappear, giving me no credit for threads read from my other machine. Worse, I start reading threads and hit refresh, and they don't update. So my home machine is not registering somehow with the forum. I have AOL, and recently had to reload the software, so I suspect it is a security setting or some such technical thing. I have added wnff as a "trusted" site, to no avail.
Which browser are you using at home? It's beginning to sound more like a problem with the cache and it not updating fully from WNFF, and instead displaying info from the cache.
