Outlook Tasks

Hi,

I am new to the Mac Outlook.  Using the tasks section I am having some problems.  When I enter the page and select a task the screen flashes and then sends me to the first task in the list.  

The screen can flash when I am not on a task too.  When I say flash it is like it jerks or has a twitch.  No problems anywhere else.  Really weird. 

I just reorder the list by a different selection (originally by the priority exclamation) and it quit, even when I went back.  The twitching has been happening repeatedly though.  Guess I have a solution but I would rather not have to reorder things all the time to get it to behave.  

Thanks.
