I would imagine your game would have two frames (one hidden frame), and the hidden frame would contain scripts to check and update page. In the bottom frame i see you might have two choices: 1. have a meta refresh which checks every 5 (or so) secs if a move has been made, and if detects a move, sends a refresh command to the top frame 2. have a php script which continually checks if a move has been made ( using sleep() function and set_time_limit() ), and if detects a move, sends a javascript command to browser, then continue detecting if changes have been made...... the implications of #2 (i would image), is the explorer icon will be constantly loading a page, so if you click stop, the game will cease hope that helps adam
