Buccaneer,
As my first suggestion seems invalid, you might want to use AutoOpen and
_OnClose event to recalculate the the time the WB has been open this time,
adding that to the previous total.

I need to create a macro where it shows how much time I've been spending
on
each project. I have #'s totaled up but have no idea on how to start the
macro. Any help would be much appreciated.
