I use Chameleon Clock under Windows 7 64 bit.
Chameleon Clock seems to be out of production now but I've used it
since Windows 3.1 and it still works OK with Windows 7 64 bit . Price
$29.99.
I'm fairly elderly and rely on Chameleon Clock for reminders & alarms.

I do believe that I am going to go with Chameleon. It does everything
Atomic Alarm Clock does. It has more bells and whistles than AAC but I will
only use what I need. There was only one slightly annoying qurik in Win 7
and that was that every time I added or changed anything it would refresh
my wallpaper and change it to "center" instead of "fill". I was using a
picture of my own so I just cured it by resizing the picture to the full
screen dimesnsions.
So I decided I'd install it in XP too. That revealed another bug (for me
anyway) and that is that it won't play wav files. I have a different sound
file for every hour (chime + "it's one o'clock PM") and they simply
wouldn't play. I noticed the default chime played OK and discovered it was
an mp3. So I cured *that* problem by mass converting all 24 of my wav files
to mp3 using Ashampoo MP3 AudioCenter. The mp3s work just fine.
Thanks for leading me to it! As well as it works, I'm surprised I haven't
heard of it before. Google wasn't showing it using "Windows 7 Alarm Clock".
Or if it was, I missed it.
