I closed a thread on accident when I ment to move it. I tried to reopen it and it said it that I was successful at closing etc. Tried again and it said the same thing.

Finally I logged off, closed my browser, logged back on and then I was able to reopen it.

This is the thread.

That has happened to me before too. I resolved it by forcing a reload of the page, doing <shift><reload>. This clears out your cache, and should allow you to reopen the thread.

This may be an Internet Explorer bug, rather than a board software bug.
