Go to the Settings (click the CD logo) and under the "on startup" click "set pages." The second box below is what you'll see and that's where you enter the URL of the game. OK out and close the browser. Now, every time you open it you will go directly to the game without loading any of the other WGT pages.
While you're in the Settings, scroll down to the bottom of the page and click "show advanced settings." In the Privacy section, click "clear browsing data" and this box will show up. Make yours look like this.
When you want to clear your browser cache, come back to this box and click the "clear..." button. :-)
