I unchecked "Continue where I left off" and TO still crashes every time I restart Chrome. But at least I don't have duplicates. I tried closing TO first but still no difference.

Every time I restart Chrome, my last Window has crashed and I have a new window with just the tabs that were open when I last closed Chrome. I do have the "Continue where I left off" option selected, but I'm concerned that I'll lose all tabs if I uncheck it as someone reported earlier in the thread.
