Whilst working on a current project I was trying to get cross-browser compatability working nicely. However when I came to load up IE’s Developer Tools I found it was loading up the window but nothing was there! I’m running Windows 7 and this seems to be the only version of windows the problem is affecting:

The solution I found is actually very simple, right click on that hidden window thumbnail and click maximise. If that fails then you could always try a solution outlined on StackOverflow. The best solutions are often the most simple!!
As if using IE wasn’t annoying enough, then this happened. Thanks for sharing the tip!
Thanks! As a predominantly Mac user I was lost on where to find the missing window.
This just happened to me so thanks for the info to getting it back…
I then tried right-clicking, select Restore, then right-click again and selecting Move. Then used the keyboard arrow keys to move something around. I then moved my mouse and little Dev window came into view which I could then resize with the mouse.
We’re back! nice.
Thanks for the tip. cheers!
thanks for the top tip!
Thanks for the tip. Seriously annoyed when working with Ie.
Thanks for sharing this tip!
