I've got a weird problem with Google Chrome. Version 28.0.1500.71 m running on Windows 7.
If you middle-click in Chrome (and most other browsers) you get a crosshair kinda thing. If you move the mouse pointer around, the page will smooth scroll. For example move the mouse pointer up (above the crosshair thing) and the page will scroll down.
But, if I middle-click inside a quoted post and then move the mouse pointer to scroll up or down, only the post containing the quote scrolls.
Like this (sorry, my screen capture won't show the mouse pointer or crosshair) - I middle clicked inside the quote from jdcarpe in Tym's post:
You can see Tym's entire post gradually scrolling up into the post title and disappearing.
This does not happen with Firefox or Safari, just with Chrome.
So it is probably a Chrome "feature". But I thought I'd mention it anyway.
