@Fil Albuquerque,
That's exactly the situation which prompted me to start this thread a few days ago, Fil ....
But, while I had the same problem as you with the BBcode editor, other A2Kers weren't experiencing the same problem at the same time.
Couldn't figure it out & thought my computer was playing up.
The functions of the code editor will probably be restored on your computer, just as mine (mostly) were. Without me having done anything at all to restore them. The next time I returned to A2K there they were again!
It's all a bit of a mystery, isn't it?
