thank you courteney, you're kind.
Yes i try chrome, internet explorer, firefox, maxthon already, and the same result even worse.
Since i'm on the site, 2 month ago, sometime it's work but lately more lag and jumpy meter, to much i think for playing well.
When it's fluid i can score between 60 and 65 and i have fun but when it's lag, the hell, i score between 70 and 80 and mainly no more fun, impossible to enjoy and playing well with to much jumpy meter.
