If you are using the dev version (6.0.408.1 dev) of Google Chrome, you might have come across a mighty annoying bug where Chrome crashes every time you put the PC into sleep mode and then bring it out of sleep.
This has been happening for quite a few days and has annoyed me to no end. In fact, I have started to save the Chrome session and then close the browser and then restore the session whenever I bring the PC out of sleep mode.
If you have been annoyed too, you are not alone, several users are facing this problem. I did file a bug with Chromium, however, my bug was merged with another bug since many users have reported the issue.
Though it looks like the issue will not be rectified soon, at-least not until Tuesday after the long weekend. Till then try using the session saver extension to save your session before you put the PC into sleep or switch to using the Google Chrome beta or stable releases.
