Closing the Microsoft Internet Explorer 7 browser or a Tab in IE7 will freeze the browser for 5-10 seconds.
Windows LIVE Toolbar is the issue. When enabled with IE7, you will run into lockups when closing the browser or TABS in the browser.
- Open IE7 Browser
- Click Tools
- Click Toolbars
- Uncheck Live Toolbar
Obviously, if the Windows Live Toolbar is not installed, you will not have this problem with Internet Explorer 7.
