SkyBrush broken in chrome?

[samim23]

hi. i´m getting great results with skybrush in firefox. However in chrome it wont run, including the demo on your site.

Console Errors (this prevents even the inital startup):
Uncaught TypeError: Cannot call method 'hide' of undefined skybrush.js?abbe35b271e9021046f87eefef3d75bde48d85b5:7435

i commented these lines out:
7435: //this.dom.hide();
7425: //this.dom.show();
now skybrush at least works again but not sure if this is a good fix as it leads to lots of errors with the shape tools.

any hints would be very welcome.
