Puzzles not Working Properly?

I first noticed this yesterday but thought the mistake must have been mine until it happened to me again with today's daily puzzle and I was able to reproduce it:

Some of the moves I enter against the puzzles aren't registering as correct.  In one case I struggled to find a better move until I finally gave up and hit "Solution" only to find that my first instinct was in fact correct but that it just wasn't being accepted by the puzzle.

I'm using Google Chrome 4.1.249.1036 (41514).  Has anyone else experienced this?

Confirmed this again with today's daily puzzle -- the first move seems to be consistently working but the second move simply isn't being recognized.

Yes, I had the same problem today.  I'm using Firefox.

It happened to me today too, Am also using Firefox, and it happened on the last move

Count me in, Firefox user here and no legal moves are accepted once you get the first one right.

@ TheGrobe - Yeah, I have the same problem with Chrome.

Maybe it's the date. April first

yea same happened to me yesterday and today I'm also using firefox

Looks like this hasn't happened for a while but it's happening to me on Chrome only.

Yeah, hadn't seen it in ages, but noticed it again yesterday.  Really frustrating because I end up trying to figure out what move is better than the actual solution.
