As the title states, I need a calandar-like program, but more flexible.

I'd like it to be similar to calandar, but be able to assign any .wav to play as an alert. Also, Alarm Clock plays a wav once every 10 seconds or so, I want something that will loop a wav until I turn it off (like a real alarm clock).

It needs to be easy to enter information into though, like Calandar. And once an alarm has gone off, it should automatically remove itself from memory, instead of having to manually delete it (like with Calandar and Task manager).

Also, with Alarm clock, the .wav list always starts at the top, with the A's. I want something that will, by default, have selected the last .wav I used.

Any suggestions? Freeware is preferable, but unlikely for something that specific. Thanks for any help.

Edit: I just thought of something else. Is there a way to display seconds on the normal task bar clock? Or some download that will do that?
