To reproduce: 1. Visit a page with an empty form field in it, or use the degenerately-simple one attached to this bug 2. Click in the empty form field 3. Command-X -- beeps, as expected 4. Command-X again -- doesn't beep 5. Command-X once or twice more After a few of these, the insertion point stops blinking, and you can no longer type into the page. If you're on a real page (e.g. google.com), mousing over links no longer shows hover feedback on the page (the cursor changes to a link cursor, but the underlines etc. don't appear), and clicking on links updates the URL field but does not load the clicked page.
