This is my work computer.

I'm constantly slowed down by pop-ups opening in new windows instead of new tabs.

Here's what happens:

- I go to Tools > Internet Options > General > Tabs Settings
- Change "When a pop-up is encountered" from "Always open pop-ups in a new window" to "Always open pop-ups in a new tab"
- Click OK
- Click OK
- Restart IE
- ...and the setting has automatically gone back to "Always open pop-ups in a new window"

I'm going crazy. Please help, and thanks in advance everyoneFor what it's worth:
