simulate mouse events broken for IE 9

I am using jquery.simulate.js for several simulated drags on my application.

Looks like IE 9 in IE 9 mode supports document.createEvent now, but the created events do not work correctly.

It still supports document.createEventObject so I forced IE to use it, but I do not think it is a good solution (this is why I did not fork):

A better solutuion, like playing with e.button values for ie9 did not help, maybe there are additional required evt attributes for IE.
