Having a problem with the Sharepoint task list web part. Basically, sometimes it works, sometimes it doesn't.. One can load the sharepoint page where it is hosted, and it will display your work items, then refresh the page and it is blank. Other times you can visit the page, the item list will be blank, hit page refresh (or the refresh icon in the web part) and it will display the items. There doesn't seem to be any rhyme or reason behind when it will work, and when it won't.

Any ideas?
