AutoCAD 2013 :: Momentary Freeze When Selecting Solids

The problem is when I select a solid, autocad freezes for about a minute.  After that minute, I can execute a command.  During that minute of inactivity, I can use anyother program or part of windows normally with no apparent degradation.  If I click in an autocad window, toolbar,etc, all the open autocad windows cloud over and the cursor turns to a spinning cursor.  Outside of an autocad window the cursor is normal.  This is how it works in the noun/verb process, grip editing.  However, if a command is issued first, then the selection of solids is instantaneous. The solid(s) are appropriately highlighted and everything proceeds normally in the verb noun approach.

I have played with a variety of suggested performance settings in windows and in autocad.  I have updated the graphics drivers so I always have the latest version.  I have a quadro fx 3700, 16gb ram, and 2.5 tb of disc space.
