that is great reassurance. The blank tab wasn't mentioned by the customer either but I needed something a little more concrete. I'm reluctant to move my browser up to IE 11 from IE 8 as I have a pending deployment and I'm not sure if all the users are on IE 11 yet. Your test helps me a lot.
Did you get the box where it asks to "Choose an application"..it defaults to Lotus Notes...with the "Remember my choice for notes links" checkbox? Maybe you already did that at an earlier point and it does "remember". I don't see that box in IE 8 either. Thank you so much again.
