Since this morning, I've been unable to scroll upwards in a Chrome browser window. Down, fine; up, no way. Strange. So, I went off to the Googles for a solution, and found the ticket for the problem.
Amusingly, it looks like ~200 duplicates have been filed of this ticket, no doubt by annoyed users like me.
Seems like an upstream problem from Webkit2, and it's been fixed in the next build, so tomorrow we all should be able to scroll both ways again.
Funny how such a small thing can be so annoying though -- what did we do back when we didn't have wheels on mice?
Yes, indeed, SmartSleep works great. It gives you a pref pane interface for toggling between sleep, hibernate and 'smart sleep' -- which hibernates if the battery is low, but sleeps otherwise. I've been using it for the past ~6 months. Without it, my MacBook would take nearly two minutes of disk activity before sleeping; now, it's sleeping happily within 5 seconds.
