Catherine asked a question regarding how to cancel a down vote here
Prior to the option you now have of explaining a downvote when a pop up box appears, it was simple to cancel an upvote made by mistake. You simply clicked the upvote arrow a 2nd time. I accidentally voted up a couple answers which I wanted to cancel immediately a couple months ago.
When I clicked the up arrow the 2nd time, a pop up box appeared asking me why I was down voting this member's answer. I didn't want to cast a down vote so I hit cancel & hit the up arrow again, which gave the member the upvote again.
Later I found out if I canceled the box which asked me to explain my downvote & refreshed my screen - my vote was canceled.
I'm a bit confused because Barry told Catherine if she wanted to cancel a downvote you click on the downvote button again. This did not work for upvotes.
I also wonder if Catherine really did cast a downvote or if she accidentally clicked the up vote arrow twice because the color change did not appear or the number did not increase immediately. This has happened to me also & the pop up box appears asking me why I want to down vote this answer. I then cancel & vote again.
I'm sure I'm not the only person who encountered this issue.
Could you please explain how to cancel a vote made in error?
The downvote message was brought in to strongly hint at someone casting a downvote that they might wish to explain why they've done it. Some site users seem to get quite upset over being downvoted. This message feature does, however, interfere with the vote toggling as you have said and I can see that it is bringing more confusion than benefit so we will be removing the downvote message feature shortly.
Sometimes if the server is running slow a vote can take a few seconds to register so a click may not appear to register when it really has. It is better to wait for a few seconds before clicking again in case this is the situation.
