Steps to reproduce


Repro Steps:


  1. Load
  2. go to
  3. Click back button
  4. Note: balls are in the same place in IE but in Chrome they will drop again from the top of the page.


  1. goto http://srvr-clw/bugs/66945 and js will fire an alert
  2. type in the address bar and go
  3. after loads, hit back button on browser and see if the alert is refired

Put some javascript that you need to fire off when the page loads no matter if they are using a good browser like chrome or a crappy one like IE. Go to a second page. Hit back on the browser. Notice the code fires off in browsers that work well. At least with Firefox they have a work around by attaching an empty unload event, but IE decides to improve performance by breaking something else and implementing this stupid behavior. I know you guys won’t bother to fix this even though it behaves inconsistently with developer tools open, but letting you know anyway…

Expected Results:

That javascript should fire off again consistently.

Actual Results:
