Making Tasks copmleted on BlackBerry disappear…

I’ve just found an interesting phenomena in regards to Outlool ’07’s To-Do bar and tasks completed on my BlackBerry (running on BES 4.1, BlackBerry OS 4.2.1 ) when marking the tasks as complete on the BB they do not not disappear from the list as they would if marked completed completed within Outlook, instead they just appear with a line through them.

This occurs because the BlackBerry does not fill out the date completed field in the task hence meeting the default requirement of Date Completed: Does not exist and thus staying in the task list (note for tasks to disappear completely they must be flaged complete and have a completion date)
