Windchill - Navigation Back Button

The search on the navigator flyout from the left is not a separate page that applies to the browser back button.  If you want to return to the search list, just click search on the left side to see it again. If you want to change the search, click Edit Search Criteria. I would recommend using middle mouse button to open a result into a separate tab. This way you can return to the tab that you did the search on. I often queue up multiple items in different tabs and close when done.  Many websites do not make use of the back button.  Just remember, executing a search or clicking on a search result item in the table does not blow away your results. Back button affects the main page of the right hand side, not the flyout from the left.
