Recently, I have a problem with IE10 (Metro).

I have one webpage(Page A) with Java script that produce another webpage(Page B) and broadcast some content to user.

In IE10 (Desktop), it works well. But in IE10(Metro), I found that Page A will be block and Page B didn't show
anything. But, if I manually switch to Page A, Page B shows something.

So, I think IE10(Metro) will block the webpage execution not on the Top . Is that right ?

In addition, could anyone give some tips to solve this problem?
