I was attempting to flag a question which is when I came across a strange thing.
I clicked the flag link which opened a Dialog where it asked for options like "very low quality" and "other" radio buttons.
Here first I selected the "very low quality" radio button and after a while, I thought I should go for the "other" radio button.
So I clicked on it, and thought of entering some content. But again I changed my mind and went to "very low quality" radio button. I clicked it and now the "flag question" button was still disabled.
Can anyone tell me why this has happened?
