I found that ietester was updated to 0.4.1 today to introduce the new features.

I didn't notice it when I was in 0.4 (fail, I haven't adjusted the page for a long time). Today I checked the page's performance in IE6 and found it was updated to 0.4.1. I will check the change log immediately, some good changes are found, as shown below:

• 0.4

Now you can capture the onbeforeunload event when you close the tab.

• 0.4.1

When ietester is used in Vista or win7, the title bar displays the Administrator information.

Now every tab is running in an independent process (like IE8 and chrome), which greatly improves stability.

Supports aero peek in win7.

Fixed a bunch of errors when tab is disabled.

If you have never used ietester or want to know what it is for, please refer to the official introduction below:
