the speedbagforum.com timer DOES NOT require you to be connected to the internet

Download this zip file: http://www.speedbagforum.com/timer.zip

Unzip it to anywhere on your PC, then open the timer.html file with a web browser (either IE or FireFox).

It should just work... That latest Windows XP service packs may give you some warnings, just click "Allow" ...

If you still can't get it to work, let me know what browser and OS you are running (ex. Is it XP Service Pack 2 , IE, or Firefox, etc.)
