I am having difficulty centering my game in a web browser. Any suggestions? The game can be viewed and played at:

The instructions have not yet been added but clicking on a hexagon that is adjacent to at least one other hexagon of the same color removes it and scores points.

Here is a portion of the html code for the game

var hasRightVersion = DetectFlashVer(requiredMajorVersion, requiredMinorVersion, requiredRevision);
if(hasRightVersion) { // if we've detected an acceptable version
// embed the flash movie
