Well I don't know if this will help anyone, but it has been slightly better the past few hours.
I upgraded my browser (Internet Explorer) to run on the latest version (7.0??) I had been running 6.0. That did help tremendously with loading the front pages at sign in. Then, after every listing, I would completely close the browser and then open up a new session. I found that if I didn't close after each listing that I would usually get hung up when I tried to load the pictures or the template on the second listing. And forget editing a picture! If I didn't open up a new session - hung up forever! Now the pages seem to be working like they are supposed to if I follow the steps above. Don't know if it's me, or if the bugs finally got straightened out somewhat. It's still not great, but it's better than yesterday.
