I am a Pocket PC user who recently tried Palm and am now back to PocketPC.
andmor, I think your problem is that the columns are too wide. Try making the columns narrower on the desktop version (you should also be able to narrow them on the Palm by holding the line in between columns and dragging).
HOW I USE LISTPRO
I have one Listpro file for my work projects and one for home. Within the @work file I have folders for my areas of responsibility and lists within each folder with basically the same field strucutre - project name, action, due date etc. My key lists are: Now, Later, Completed, Someday. I also have a "This Week" list which has a line item for each day. This this is at the top of all my lists and folders. When I do my weekly review I enter the next actions for all my projects in the the "This Week" list under the appropriate day.
I keep the next actions for all my projects as indents under each project (projects are written in CAPS, actions in regular). Elaborations on projects and actions go in the notes section of the project or next action. As I go through the week I may glance at the Now list if I get through my This Week list. When I do my weekly review I move items from the Later list to the Now list or vice-versa as priorites change. In my Now list I flag (my flagged items turn blue) any items that are currently in progress. "Now" means projects to work on this month.
I find this system really works for me in making sure I do what needs to be done that week without having to look through all my project lists each day. When I first started with GTD I had everything in one list and it was too unweildy and overwhelming for me to use.
When a project is completed, I add the completed date and move it to my completed list. This is invaluable when it comes time for staff review to see how much work I've done!
