I took the July Flex on my Macbook air and highlighted just fine. Off and on I have issues scrolling but resolved that by just plugging in a mouse. There was no problem taking the test with a plug in mouse and it is a much more reliable way of ensuring that the scroll and highlight functions are going to work consistently for you every time.

How did your Macbook air run the ProctorU program, was there any speed issues or issues more generally?
