I need to understand how the activities log works. When it says the invoice has been viewed is there a way to know who has viewed it.  I sometimes have CC people other than the original recipient.  It also appears the activities log also shows every time I view it.  If it is showing the times I view it, without telling me that it's me, then then I really have no way of knowing if my client has seen it.  Also it seems that if I have it open then open another tab and then go back to that tab it records that as another instance of it being viewed, which adds additional confusion.
