O.K. I checked this and it is pointing to where all of my thumbnails exist. Funny thing is that I am abble to see the thumbs if I enlarge them, this is the same whether I am viewing audio, video, or images. The thumbnails are there they just are not viewable it seems at small and medium sizes. I have checked the offset medium and offset small thumbnail setting and they are the same as the Large thumbnail offset settings. Is the jrworker.exe responsible for gathering these thumbs? Could there be a codec that is not compatible with the new version. Normally when the thumbs are being created the ffdshow icon keeps popping into view in the notification area, it does not seem to do that now. This could be something simple I just can't think of what it is. Thanks for any light you can shed on this.
