I've been waiting for this new release for the X3F support (Irfan v3.97.) If you haven't used Irfan before, give it a try. Program is freeware(GPL), been around since 1995, only 800k in size and has many featurs that the SD software does not have. It is built to run fast and efficent. It has a lot of keyboard shortcuts as well as an excellent thumbnail browser. I've just installed the new version and confirmed that it works with the X3F from the SD9. It took 6980ms to load 8mb image in memory on a 5400rpm hd.
