We just got a new computer and at the same time switched from dial-up to wireless. Since then I've had problems using this site. I'll log in, but when I try to click on "New Posts", it will tell me I need to log in or register. Also, for many of the threads, I am unable to see the pictures, and if I try to reply to a thread, it takes several tries before I'm permitted to and don't get the screen asking me to log in again.

Does this sound like a problem with my internet connection, or do I have to change some setting on my computer? Any ideas?
