The right-hand banner ad
 

This is really bugging me. If I switch programs while reading/writing a comment, when clicking back on the browser window, it's usually on the white-space to the right.

Unfortunately the entire section to the right of the comment box is actually hyperlinked to the banner ad, regardless of whether you actually click on the banner itself.

I have accidentally clicked below those banners several times, and obviously it loses the comment I was writing, which is a pain.

I guess the solution is to have the ads open in a new window.

Time to use the keyboard shortcut to cycle through your active programs.
