I have decided to try David's way, and see how it goes. That means not using my 3rd party app to ive me Palm ToDo "ticklers." Instead, I am putting some things in two places. I put a note in calendar (undated) on the day when I really has to be done. Then I put a context related ToDo in my ToDo list to remind me. No dates attached to the ToDos.
We'll see. I notice already that it means that I go to my context lists more. Otherwise I tend to view the ToDo ticklers as "urgent" when then aren't (yet).
