I’ve never seen this before. I got this message today in Mozilla 1.4a:

a script on this page is causing mozilla to run slowly...

Not sure how useful that is for the average end user, but of course the average end user is not using Mozilla. I suppose we can expect this feature to be rolled into Netscape. It may be nice to make it clear that it’s not necessarily the browser’s fault that a page loads slowly, if only to lessen the chances of people switching browsers for some perceived speed improvement. Hm.

I’ve always been bothered by the options on dialog boxes like these. Let’s see, click OK to abort (i.e., to cancel), and Cancel to continue … huh?
