Problem with Grid in Google Chrome since last update

Hi, I've been testing out ActiveGrid for a little while and it seemed to be working fine, but since the last update on Google Chrome it now randomly stops working.

The grid will not load, having a js error at line 73 of aw_fire.js saying it's unable to set offsetHeight properties on non existing object. I think that this is the faulty part:

AW.Grid.Controllers.Size=(function(){function init(){this._rowHeight=this.getContent("sample").element().offsetHeight;

What is weird is that if you refresh the page, it will sometimes work, sometimes not, with nothing else changing. I have not seen the error happen in IE.

Do you have any idea what could be causing the issue?
Thanks,
Tom
