I frequently (but don't always) run into an issue with Chrome on my PC where reviews will load without any scrollbars:



When the page first loads, the scrollbars will be there for a fraction of a second, but some seemingly-ad-related Javascript takes them away almost immediately. I haven't run into this in Firefox, and this has never happened in the forum -- just reviews. It's not just me; at least one DVD Talk reviewer has reported the same.

If it helps, this is what Chrome's console reports.



By comparison, this is what Chrome's console reports when the page loads with scrollbars:



It looks like the two bits of Javascript referenced in the scrollbars-less version and not in the functioning version are:

https://s0.2mdn.net/ads/richmedia/st...8572/hammer.js
https://s0.2mdn.net/ads/richmedia/st...oductToggle.js

I'm not sure exactly which ad is triggering this.

Does NoScript have a Chrome add-on?

Another example of this happening (note the lack of scrollbars):



I figured out the problem. An ad is adding overflow:hidden to the body, so anything outside of the current view is completely inaccessible.



I've highlighted which tag it is / which ad it is. Please fix this when you get a chance.

I PM-d IB about this.

Reporting to tech -- thank you guys!
