Just lost a lot of important tabs I had left open in Chrome even though I have is set to save sessions. I don't even know how I'm going to find half of that stuff again to resume what I was doing.
I came home and found my notebook on but with no video. I don't know if Windows Insider Preview updated my Windows 10 build or if it locked up because I closed the lid too fast after telling it to sleep (a problem it seems to have since upgrading to Windows 10). Regardless, I booted and waited until thing seemed to settle before launching Chrome and was comforted to see the "Restore" button. Unfortunately, it dimmed and my mouse pointer started spinning when I attempted to click it. I waited several minutes and saw that the option to open a new Chrome windows was available, but I didn't dare use it because I didn't want to start a new session and over-write the session I was attempting to recover. I checked the Task Manager and found all four logical CPU cores pegged at 100%. None of the processes were using over 40% but I waited until things suddenly dropped under 5%. Chrome still didn't respond. I waited longer and then a Chrome dialog popped up and said that Chrome was not responding, offering to "relaunch" the window.
The dialog was from Chrome and not Windows, so I believed it was the best chance of recovering my session. The unresponsive window closed but did not relaunch. Eventually, I launched it manually and I got the "Restore" option again. Unfortunately, it just restored the previous session that went unresponsive. It was now responsive but with no option to restore the prior session before that.
Ugh.
