blurred bridge pix in CS6

Normally I do my rough editing and weeding out of unwanted images in Bridge.  I press the spacebar and the image fills the screen, and then I can press a number to rate it and press arrow key to go to the next.  If I want more detail I use + or use the mouse wheel to go larger.

Now however, after pressing the spacebar and getting the full screen image I get out-of-focus images that would cause me to delete them, if I hadn't already known that they were not really blurry.  When I enlarge the image by the methods indicated, I get a sharp image.

Previously, it sometimes took a few seconds for such an out of focus image to fully load and snap to sharpness, but now it could sit there for hours unchanged.

I have tried restarting the computer, reset the bridge cache, looking at images within a single folder, instead of the multifolder search of all the folders on my recent trip and nothing is changing this.

These are Nikon RAW images and I can't continue editing in this situation.

I took 2 screen shots with a cell phone to show the smaller (unfocused) and larger (focused) images, both taken at full screen size. which leads to 2 more questions.  Where is the button to attach them to this email.  And why do I have no choice for Photoshop to open them with directly?  If I double click, it is Nero media home viewer, and if I use the file menu, there is no 'open with', just 'open', which is the same result.  I need to either go to Bridge and open them from the folder they are in or open Photoshop and seek their folder, when I want the simple step of opening directly to be into Photoshop.
