thumnail preview problem

[Brooke White]

This behavior can occur if the file association for the
type of file that you are trying to preview has been
changed by a third-party program: This happened to me when
I installed corel software, and now I can't view
thumbnails, except for psd files. How can I view
thumbnails again?

<SNIP> I installed corel software, and now I can't view
thumbnails, except for psd files. How can I view thumbnails again?

To resolve this issue use Regedit to associate the file extensions with the thumbnail
image handler. For more information see the following Microsoft Knowledge Base
