There is no point in clicking the refresh button, instead it might even make the situation worse.(atleast it does for me).
I am using my sucky internet connection and windows 98 computer, still i manage to play well. Sometimes you people might have 3 secs delay, or how long the delays are nevermind that.
If you cant see something on the page when loading it, it might be because your firewall or some other thing in your settings is not allowing to show pop ups.
As Budly said, it also might be some javascript problem, so i would suggest to get the newest java and also check your internet settings if you have the highest protection rate on what might cause that some things might see missing on the sites, personally i prefer to have the internet protection settings on normal, since i play a lot of internet games. ( a lot less whining from your computer )
