Outlook 2003 Disappearing Tasks

Somehow my list of tasks has disappeared from the task view in MS Outlook 2003. The weird thing is there are some tasks showing, but they are very out of date. I suspect the ones that are showing are those associated with my archive .pst folder, as the most task recent item happens to have a date very close to the date of the latest email message in the archive .pst file.

Another clue - I was able to see the missing tasks briefly, when I somehow was able to get the folder "Tasks in personal folders" to show up in the navigation pane in the Outlook Task view. But now it has disappeared, and all I have is a single folder (?) in the navigation pane labelled tasks.

One other clue - there do appear to be tasks in both my outlook.pst file and my archive.pst file. When I right-click on the "Personal Folders" icon in the "All Mail Folders" box, and then hit the "folder size..." button, it comes up and says I have 143K worth of tasks in that folder (77K of tasks in the archives folders). But for the life of me I can't seem to find out how to view them all.

I tried pstscan to repair my outlook.pst file, but that didn't seem to do anything.

Can anyone suggest a way to get them back in view?

Thanks!
