I had to reboot my Windows 7 box, and had two Chrome browsers open, each with about 10 tabs. When my box restarted, the last tab set I closed reopened when Chrome came up, but when I opened another Chrome browser the same set was the only on in the "recently closed" selection at the bottom right (Chrome version 20.0.1132.47)
Is there a way to reopen that older tab set in Chrome, some history section I can look at? I have no recollection about the individual tabs in the browser window.
