2007 SolidWorks Explorer Search Result Errors

Hello All-

Please see the attached .jpeg. I had to block certain information.

1. I Search for files and get the results.

2. On some of the result files, I can select/click on each file,get a preview and information.

3. Yet, on others, when I select/click on the file, I get nopreview and no information.

Any suggestions?

Thanks in advance.
