ie8 var w= window.open() - “Message: Invalid argument.”
check this page out: http://jsfiddle.net/S7Crc/
notice that clicking on click me opens a window properly in firefox but not in internet explorer despite the fact that the window.open is triggered by the user...
how do I get Internet Explorer to properly execute window.open and have it behave the same with Firefox? (note that I need to set the width and height of the window so a simple target _blank or target _new are NOT viable alternatives)
