Is the Internet Explorer 8 Developer Tools window embeded/docked in IE8 window too (just like IE7 dev tool)? It's a popup window in my environment.

IE8的开发工具是嵌入在 IE8 窗口里的吗（像IE7的开发工具那样）？而我这里却是一个弹出窗口。

everytime I hit shift R or ctrl R, the stupid ruler apears on my screen. I don't know how to diasble this but it's more of a nuisance then a help. I use an online CMS and it's difficult to write code like DR when the control keeps popping up.
