Connect X6: Thumbnail with SVG and CPT not working

I just upgraded to X6. Connect show thumbnail of CDR files, but none of SVG clipart, neither CPT files.

I have Corel Graphic windows shell extension installed. Actualy the problem is the same with windows explorator, I can see thumbnails of CDR files, but none of SVG neither CPT files. I thought Connect could allow me to see those thumbnail.

it was the same problem with connect X5.

What could I do to see the CPT and SVG thumbnails ?
