I'm looking for an alarm function:

[hedgehog]

Here's the deal: when I'm working, I lose track of time. Now I've read that I should stand up and move around at least every 20 minutes. I'm running Windows XP. Is there function that I can use to say, dim the screen every 20 minutes?

2. how about a popup message?

Paste the following into Notepad and save it as "C:\Timeout.vbs"

Option Explicit
Dim CountDown
Dim message
Dim WshShell

Set WshShell = CreateObject("WScript.Shell&quot
message = "Hey, it's been 20 minutes!"
CountDown = 1200

Do While CountDown > 0
WScript.Sleep(1000) '** Sleep for 1 second
CountDown = CountDown - 1
If CountDown < 1 Then
WshShell.Popup message, 0, "Time is up", 48
CountDown = 1200
End If
Loop

Start the reminder with the following:
Start -> Run...

WScript C:\Timeout.vbs

You will be reminded every 20 minutes that "Hey, it's been 20 minutes!"
The timer stops until you click the "OK" button in the popup. 20 minutes later... you are reminded again.
