Create a search that returns a list of items, select one item, then hit back button and you get

"Confirm Form Resubmission
This web page requires data that you entered earlier in order to be properly displayed. You can send this data again, but by doing so you will repeat any action this page previously performed. Press Reload to resend that data and display this page."

This is very annoying, as I only use search 2-3 times a month, and it is more natural using the keyboard instead of using the mouse.
