Well, one simple thing that you could try is to click the quick delete button () in one of your posts.
If Javascript is enabled, then you should get a message asking you if you really want to delete that post.
If Javascript is not enabled, then nothing will happen.
Also, did you try another browser (Firefox for example) and see if this still happens?
