IE8 / IE9 developer toolbar is empty and frozen

Question

Something went wrong with my IE8 developer toolbar, this is what I get when I open the toolbar:

The browser itself works fine when I disable the toolbar though.

The last time I was using the toolbar, I was debugging javascript. I don't know why it suddenly stopped working. Things I tried:

1. Restarted computer.
2. Switch to Firebug Lite, but it does not allow javascript debugging. This is a feature I really need.
3. Installed IE9. Developer toolbar is still broken.
4. Deactivate / activate IE8. It is not easily possible to completely deinstall IE8 from Windows 7, but I did deactivate it, but to no avail.

If anybody either recognizes this problem, or knows a workaround, please let me know.

Answer 1

By using the IE 8 Developer Tools not working In Windows? fix, I actually got it working again. After maximizing, resizing and dragging the toolbar, at a certain point I was able to snap it back to the screen without this bug.
