GetAxis for MouseX for web player.

I have a simple game where the Character moves left to right as you drag the mouse left and right. Under 2.6 it all worked great in the web player, but under 3.0 I no longer get samples as soon as the cursor leaves the game screen on Chrome or if it leaves content area of the browser in IE.

Since this game tends to get frenzied towards the end with players moving the mouse left to right, often beyond the edge of the game screen or window, game play is now severely compromised as the character stops moving if the mouse goes beyond the screen bounds.

From research this now seems to be a feature of 3.0. Anybody have any suggestions on how I could get the old behavior back? Is their a different call besides GetAxis that I can use to always get correct mouse coordinates, even if the mouse is beyond the play area in the browser?

Thanks!
