Please note that we have identified an issue with Chrome’s new scrolling method in WordPress / vBulletin.
As of the latest Chrome update, Google has removed the up / down navigation and scrolling arrows in the main browser and within drop-down boxes. The problem area is highlighted below.
At this time, due to a bug introduced with this version of Chrome, the scrolling function within the review drop-down navigation box has been disabled. As such, you may need to use the up / down keys to navigate past Page 19 within the pull-down box in some reviews.
Google has been made aware of this issue, under no circumstance do we support it and it has been discussed widely [URL="http://productforums.google.com/forum/#!topic/chrome/KCvRExwNxdE"]on the developer forums[/URL].
