I've had the same problems mentioned in this thread on both of my computers since last week. I can't bring up the cache pages from the e-mail notification links, they just sit with a green screen. When I would search on the "map it" from my profile page, I could only see the cache "boxes" on the map page, but no streets. I would try to bring up the cache page from the "map it" page and it would "lock up", getting only a green screen with the curser arrow and hourglass. No amount of "refreshing" did the trick. This evening I finally decided to jump IE ship and download Firefox. In less than 5 min. everything is good here again! Should have moved on sooner I guess! Happy Caching!
