Can't switch to fullScreen in Phaser 1.2

[UnlimitedX]

Here the issue when pressing F2:
Uncaught TypeError: Cannot set property 'imageSmoothingEnabled' of null phaser.min.js:12

Here the code:
this.F2Key.onDown.add(function() {
Jiun.game.scale.fullScreenScaleMode = Phaser.StageScaleMode.SHOW_ALL;
Jiun.game.scale.startFullScreen(false);
}, this);

All was working very well in phaser 1.1.x.

Got the same error, I just removed the "false" within "startFullScreen" then it worked.

This should work fine now. It won't try and set anti-aliasing on the context unless you're running in Canvas 2D and not WebGL.
