selection isn't very reliable with two clicks

On my Chrome 24 on Ubuntu amd64, the code as-is fails to select the option more than half the time. I added some "sleep 1" to no avail. According to [1], selecting the option appears possible with a single click, and this works better in my environment. So I'm committing this change.
