My school requires this to get onto the WPA2 network here. Does anybody have experience with it? I installed it a few months ago, and soon after my MacBook Pro slowed to a crawl, getting the beachball even opening a website, etc. I had to reinstall SL and didn't reinstall thinking that this was the issue. However I'm not 100% sure. Should I install the app again? Or is it pretty sketchy? There isn't much hard information out there about it.
