User is running Windows 7 Pro 64-bit with IE10. She connects to a secure government website and logs into it. Once logged in, she clicks a link which opens a small popup IE window. A short time later, a couple of other small popup windows are supposed to open which are not IE windows but apparently java windows as the icon on the taskbar is the java icon and not the IE icon as for the main window and the first popup window. One of the java popup windows has links to click on to view various reports.
This user was having no problem performing the above. Then her PC had Office 2013 installed and she says some other updates though she has no idea what (I know IE was not updated). Since then, the java popup windows do not open, only the first IE popup window opens.
She can go to other Windows 7 Pro computers with IE10 and has no problem with the site and the popup windows. She can also use an XP system with IE8 and has no problem.
I have disabled the popup blocker (though I was sure that wasn't the problem), installed JRE6u45 since she already had JRE7u45. I've tried to match her security and advanced settings to another PC. I've done a complete IE reset. None of these things have worked.
I've never run into this type of problem before. I don't know if the problem is in IE or in Java or somewhere else. I'm really stumped on this one and I would appreciate suggestions as to where to look for the cause of this.
