crazy preview issue with PS CS5

hey!  have rather odd issue i'm dealing on 2 separate digital painting projects

 

on desktop have psd file, , throughout day hit space bar quick preview of image.

 

today had been using cmd+c , cmd+v on selection wanted on new layer, wouldn't it.  saved image, , restarted ps, , seemed trick. -- able copy/paste fine.

 

so issue is, when hit space bar on desktop view image, seeing piece trying copy/paste!!

 

the rest of image on thumbnail there, , of layers visible inside document. 

 

kinda crazy!  imput!

have saved additional channels (as seen in channels panel)?

those seem throw preview.
