Can no longer be used after clicking on "Create Attempt"

[OgreTransporter]

I clicked on "Create Attempt". Now nothing works anymore:

It's a minor bug. Simple work-around: Don't click on that column heading ;-)

If you log out and log in again, things should start working.

This will fix that #28

I;ve just pushed our latest code, which already had a fix for this.
