Just released version 0.5.4 of XWFIM.
Change: Renamed Settings.bin to xwfim.bin since people seemed to run both XWFIM and XWFRT from same directory and this caused problems
Change: Updated book cover image and URL when clicking on the book image
Change: Delete any old viewer directories before unzipping a new version to avoid file inconsistencies across viewer versions
If you get a crash about "key not found" or similar, delete settings.bin and restart. Prior to this release, both XWFIM and XWFRT used the same file, settings.bin, to store configuration data. If you can both programs from the same directory this would cause issues.
This update will download automatically once you start XWFIM. Click the lower right corner of the application for details.
