Hello, i am experiencing the same issue as discussed in https://social.msdn.microsoft.com/Forums/ie/en-US/newthread?category=iedevelopment&forum=iewebdevelopment.
I am using Javascript and window.open to open a named window. Right after, i am trying to submit a form with the target showing at that window. This Javascript code is inserted through Flex. When i am opening this from Chrome or Firefox or IE11 using a local Tomcat server it works fine. When i open it from my 2008R2 Windows server it works fine on Chrome and Firefox but in IE11 it opens the new window blank and then tries to open the form in the parent window instead of the new one. Trying many different ways in some cases, it just opens a new tab instead of opening the url in the new window.
I believe the issue is very similar to the problem described in https://social.msdn.microsoft.com/Forums/ie/en-US/newthread?category=iedevelopment&forum=iewebdevelopment, yet i have enabled User Account Control: Use Admin Approval Mode for the built-in Administrator account on both server and locally and still the result is the same.
I also tried opening the window with window.open and then using the navigateToUrl command of flex to redirect the window to the right url and still the behavior was the same.
I would appreciate any advice,
thank you in advance.
