On this post: Format Currency string to integer
I initially upvoted the first poster (Khalos), then I noticed that he used 'double' not 'decimal', so I undid that vote (within about 10 seconds).
I note now that he has updated his answer to use 'decimal', so I'd like to upvote him, but instead of being allowed to do that, I get:
You last voted on this answer 34 mins ago Your vote is now locked in unless this answer is edited (click on this box to dismiss)
Amusingly, it happens that this answer was edited, so this error message is wrong in two ways.
Clearly, when I view the post myself it does not show an orange upvote button (to indicate that I had, indeed, already voted).
It might be worth noting that I have voted on a comment to the post (the posters own comment). It may be a bug on the logic/handling of this vote that is causing the issue.
-- Edit #2:
As usual, forays into the meta forum are a painful experience. I won't comment on this question further, but I leave it in place incase another person decides to report this bug.
