Gecko-based browsers (Camino & Firefox tested) let the script run away for a few seconds, then present a warning dialog asking whether the script should be allowed to continue. Perhaps something similar would be appropriate for Webkit and Safari? Opera seems to allow the script to go on indefinitely, but via threading the script doesn't take over the whole browser or seem to use as much CPU. Something as simple as this works: {{{ <script> function doIt() { var i = 0; while( i < 50 ) { } } </script> <button onclick="doIt();">Drink Me</button> }}} 31757 1 ap 2006-02-07 13:30:36 -0800 This report has been filed earlier, but the future of this issue seems to be with bug 7080 :) *** This bug has been marked as a duplicate of 7080 ***
