Today, I have flagged a question as being off-topic here (as the question seemed to be more about Windows than about Ubuntu), then, I had a second thought (the OP was a beginner in Ubuntu and closing down his question might be a reason for disappointment and confusion, and besides of that, we should admit that, sometimes, beginners are not yet prepared for the change, so they do want to go back to Windows).
Anyway, when I wanted to retract my flag, I noticed that it's not possible. Here's the screenshot:
Now, where is the good old button saying me to retract the flag? I can't see it.
How can I cancel my flag in this situation?
Note: You may question my reasons regarding my flagging behaviour, I admit that, but the technical problem is still on.
