I have read the related questions on this topic, but haven\'t yet found a solution to this issue. I have a simple javascript function that calls window.open when a link is
I noticed something similar.
I have a window opened using IE function showModalDialog. On this window, I have a button that calls window.open. This call returns null. Then I opened the same page in normal window, not in modal dialog. This time the button returned null as well, but IE told me that web page wants to open pop-up window wand this was blocked. It gave me an option to unblock it... and it started working in both cases - modal and regular window.
It seems that in Modal mode in IE, IE does not show warnings like popup blocked.
