Hi Brendon,
Since the Q.Alert class is inheriting from the window class you can
simply use the hide() funciton.
You wight need to force it to hide by passing true as the fist
argument:
var win = new Q.Alert(...);
...
win.hide(true);
That should do the trick.
You can also add 'closeButton' in the options like so:
var win = new Q.Alert('title', 'message', { closeButton: 'left' });
Good luck!
