Photoshop :: CS6 Error When Trying To Save A File

I'm getting the following message when saving in Photoshop CS6 Extended:
 
"Could not save "G:...\_0008_DSCF7826.RAF.tif" because the file is already in use or was left open by another application."
 
The issue NEVER occurs if Bridge CS6 is not running.
 
The problem occurs intermittently when saving individual files, and nearly every time I try to run a batch operation on multiple files when Bridge is running.
 
Since a huge part of my work involves batch processing files, I spent some time trying to narrow down the cause. I did 10 Batch processing test runs on twelve 100MB files. My batch process used the "save and close" option in the Batch dialog. I think the issue involves Bridge because:
 
The issue DID NOT occur (in 10 test runs Batch processing twelve 100 MB images with the "Save and close" option checked):
 
If the Batch action was run through the Photoshop menu with Bridge turned off.If the Batch action was run through the Photoshop menu with Bridge running & Bridge's Performance and Handling settings for Thumbnails set to "Do Not Process Files larger Than zero MB."  
The issue ALWAYS occurs:
 
At some point when a Batch Action involving a "Save and Close" command is run through the Bridge Menu. My Batch processing generally involves 12 files.  Usually, one or two files  process, save and close properly before the error message appears. I've reset the preferences for both Photoshop and Bridge several times with no results. I'm running 64-Bit Windows 7 and 64-bit Photoshop CS6 Extended.
