1. I entered an invalid number for "Goto Item" (77)

2. I clicked "Goto Item"

3. Because item 77 doesn't exist, a helpful screen informed me.

4. I absent-mindedly pressed F5 (Refresh in IE)

5. I got an "Error 500" page.

6. I hit F5 again

7. I got the Login screen

8. Logging in again, I was immediately redirected to the error page.
