Hi:  I have the same problem as the poster.  Here's when it happens:

I have a 2nd "extended" screen (larger monitor).  When I drag Quickbooks onto the extended "screen", the hover-to-a-magnifying-glass doesn't happen.  It remains an arrow and is unclickable.  However, when I slide Quickbooks back to my laptop, the hover works and the click for detail works.  Is there a solution for this?  Very annoying.
