Google Chrome: Vertical scrollbar disappears on some web pages, maybe due to a strange toolbar

Question

One of my customers have trouble viewing some of the pages on our website. Specifically it is the vertical scrollbar, that disappears on some pages.

She is using Google

Answer 1

I ran into this situation where my "yahoo finance" page lost its scroll bar (after reinstalling Chrome). I only had one remaining extension left running (one I trusted). It was AVG Secure Search (I used AVG antivirus). I disabled it and the scroll bar appeared the next time I opened Yahoo Finance. Interestingly, I had left the old, missing scroll bar page open. It was unaffected.

So, AVG Secure Search extension interferes with yahoo products.
