ACDSystems the authors of the excellent image browsing / viewing application have today announced ACDSee 4.0 (Windows). ACDSee has been the browser of choice here at dpreview for some time, and it just keeps getting better. New features include a new interface, a full screen file-browsing mode, 10 new multimedia formats, enhanced slide shows, zoom level by pixels or percentages, catalog photos from CD (for offline browsing), browse thumbnails and file details in a column view and 'first frame thumbnail' for video files. Download a free trial, buy ($49.95) or upgrade ($34.95) today. This version also supports Canon RAW files (CRW) - although VERY SLOWLY.
