I have a problem with a child window using the parent's FORM to do a submission/post to open a new window. This is being blocked by IE7. This is happening when accessing an external website that is not listed in the IE7 pop-up blocker allow list.

If the current page does a FORM submission/post to target "_blank" then this is allowed and a new window pops up. However, if the new child window calls opener.top.document.someForm.submit(); then this is blocked.

I am developing a website and I don't want to tell users how to setup their popup blocker. I wish to find a way to get around this problem. Does anyone know how to allow a child window use it's parent window's form to do a submission/post to target "_blank"? without being stopped by IE7 pop-up blocker?
