Thanks, Wally!
I just have tested YoWindow on the New iPad.
It launches flawlessly.
I hope we will find the source of the problem with iPad 2 launches.
It may not be just iPad 2, but something context specific, like language or location.
Don't bother with it now, in the closest future I will add diagnostic tools that will help us to find out what is going wrong on startup.
Get YoWindow weather app for your phone or tablet.
