Firefox Wheel Click Problem Fixed
(with comments)

I fixed that Firefox mouse wheel click problem. Previously, Firefox users who clicked a link using the mouse wheel, found that they had to click somewhere in the document in order to regain the ability to scroll with the mouse wheel.

I noticed that same problem at Phillipp Lenssen's Feeeds site, so I examined his CSS file and compared it to mine. I noticed that we both used the following style attribute:

overflow: hidden;

When I removed that, clicking and scrolling worked properly. Clearly, it's a Firefox bug. I used that attribute in order to avoid making the column wider if someone posts a very wide image in a comment. But I'll gladly give that up if means fixing the annoying mouse wheel problem.
