Board won't show up in online chess
This probably won't help you, but you might try waiting a while. Sometimes it takes my pages the better part of a minute for them to correctly load all the way. Just thought I'd suggest it just in case you hadn't already tried it.
I saw the post about email chess, but my board randomly won't show up in the online chess setting. It did for a few weeks, and now randomly nothing. The rest fo the entire page loads, but the board loads up blank with no pieces. Even the daily puzzle won't load.
From the post about email chess I've gathered the following data on my system.
Firefox 3.0.8
Cookies = true
Java =true
Firewall = false
width/height = 1440/900
broadband = true
platform = Win XP
Anyone have any ideas?
