Internet Explorer 9 won't open popup windows
Some times Internet Explorer 9 will not open popup windows. It was first discovered while trying to download a file but seems to be happening for other popup windows as well.
It's a bit hard to exactly describe how to trigger this since at first everything works normally and then it stops working. There is no error message that is visible for the user. Opening the developer tools (F12) and switching to the 'Console' tab it is possible to see an error message:
SCRIPT70: Permission denied
Once it has stopped working for a given popup window it will not start working again, but other popups may still work. There are some workarounds:
- Closing the tab with BASE and then opening a new tab and logging into BASE seems to help for some time (until the problem appears again).
- Adding the BASE site to the "Trusted sites" (Tools -> Internet options -> Security) list seems to prevent the problem from appearing in the first place.
