In ACT (2005 and newer)
1. Tools > Preferences...

2. Click the 'Calendar and Scheduling' tab
3. Click the 'Scheduling Preferences...' button

-In the Activity type settings window
3. Click 'To-do'
4. Change Duration to 0 minutes
For good measure:
6. Uncheck 'Enable activity conflict checking'
Also
7. Make sure 'Default to timeless' is selected
8. Click OK

That's it!
