For some reason, one of my content types scrolls to the comments section of the node every time it loads (instead of starting you at the top of the page). Disabling comments for that node solves the issue, so I know it has to be something to do with the comments. The weird thing is that none of the other content types have this issue - only one. Any ideas??
Edit: With further testing, hiding the form elements in the comments area seems to solve the issue (setting .box form to display:none). However this is not ideal, as there is no way to post comments then.
