It's freezing with 7-8 tabs open. I'm forced to restart the machine. Oddly, I can't use command+alt+esc to force quit the app. At this point, I have to resort to using another browser if I'm going to get any work done. I noticed it happening after updating to Yosemite. I also have an app called Time Out installed which might cause an issue. I'm still trying to determine why it locks up. I read on another forum that people were having issues with trackpad devices and Chrome settings. If anyone can shed light on this issue, that would be great.
