I hate to bring this up as I am not shure if it is a site problem, or my slow internet speed.
Often when viewing a forum page here the page [freezes] if I take too long reading or composing a reply or post.
The navigation links quit working and I have to refresh the page to get going again. More of a nuisance really than a real problem.
Sometimes even the post/reply button does not work and when I refresh the page before posting I loose the post and have to rewrite it.
