Hey Manish,
The 3rd option you provided worked great. I'm not sure what is up with the API in IE 10 but I stopped the code before setting the showTooltips = true & in IE it was actually false (chrome and I'm assuming others have it true). One caveat to doing this is that it doesn't work if you try to pass in {showTooltips: true} as the options. It also didn't work if I tried to set it immediately after calling the constructor. I ended up doing it later on in the process; immediately before calling activate.
Thanks for the suggestions!
