Pivot Table Field List Is Only Partially Displayed
 

My Field List is only partially displayed. The bottom 70% is missing (just
blank blue space). This looks like a bug since there is no bottom
border...it's like the bottom is just cut off. I have a 20" wide screen LCD.
Is there a way to get the entire Field List to show? I've never experienced
anything like this and I'm pretty experienced with Excel. Thanks.
