Thanks! I already made the EXIF fix in my local version (slightly differently but same basic idea), but I didn't do anything abou the fullscreen thing yet. I'm a bit reluctant to use that fix because it seems a little kludgy and might not be needed soon anyway, but for a stop-gap it's a good enough idea.
Anyway, the version in trunk is in some half-finished state, and may or may not be a good idea to run normally. If you want something that works a bit more reliably, check out the older source for 2.0 from tags. XADMaster and UniversalDetector come from The Unarchiver, you can grab them from there if you want to build a proper version.
