Hi,
problem with PDF-XChange - no thumbnail in DO's thumbnail-view, just the PDF-Icon.
Outside from DO everything works fine - thumbnails are displayed on desktop for example.
Maybe, I have to change something in the DO-Plugin-settings?
See this thread: PDF thumbnails with PDF-XChange Viewer.
Support for the newer thumbnail provider method will be included in Opus 10.
Hm, is everything known about the release of Opus 10?
Not much has been announced yet.
