Collaborative Tasks Manager

[danson]

Hi Guys,

This isn't really a UR topic but you are the ideal demographic to ask so I hope you don't mind.

I'm looking for a non-web based task list manager that will run on all computers in my office. Each person will have their own list and be able to add tasks to their own and other lists which everyone can see. The program should synchronise over a LAN (network).

Looking for something fairly lightweight - I'm sure Outlook can do this via Exchange but that is overkill.

Any ideas for a program that would do this job?

Many thanks,
Daniel
