Tooltips don't work in IE7

So I was having this problem in IE7 with the tooltips showing. I tracked the problem down to the qtip.js file in the module on line 204:

  'left_center' : 'right_center',

I simply just removed the ending comma and it worked.

  'left_center' : 'right_center'

I've had problems in IE7 before when I ended an object's last element with a comma.
