How odd. I don’t see either of these problems. Can you tell me a bit about your setup? Are you on Windows? What browser? I actually don’t think ILP controls the delete key functionality at all, the text boxes are text boxes, their functionality is controlled by the browser. Do you have the problem on other sites?
For logins, do you block cookies by default or have an ad/tracker blocker? Have you flushed your cookies? When you look at the site information, how many cookies do you see?
