The easiest and quickest way to play is use 1 browser for WGT and nothing else and set the start-up page for that browser to the game client window. You never have to hit the play now button.
In your browser settings in on startup click on
Open a specific page or set of pages.
Click on set pages
type http://www.wgt.com/gameclient.aspx into the box
Click ok.
From then on every time you open your browser it opens to the game client and you can play without having to worry about the play now button. It also opens the gameclient page much faster than clicking on play now.
