I'm using Google Chrome 6, Windows XP SP3, and Confluence 3.1.

When I attempt to check off a task in display mode, there is a pause, and then the checkbox is cleared. When I attempt to add a task in display mode, the task field grays out, and the functionality is inactive until I reload the page. After either case, Google Chrome's console shows the following:

Refused to set unsafe header "Connection"

In reading a little about what typically triggers this response from Chrome, I thought that this would be better labeled as a bug, since it seems most browsers will soon respond the same as Chrome does now.
