Since Doors CS 5.8 Beta 3, a bunch of bug fixes, improvements, and features have been implemented. A special focus has been placed on the Associated Program (AP subsystem) tools and GUIs, including completed FileOpen, FileSave, and FileSaveAs routines. A new icon has been added for associated programs with no known reader, and a small bug with type detection has been repaired. Several minor quality-of-use issues have been resolved, such as more debouncing and alpha setting masking. GUI tools that manipulate memory have been modified to return information on the memory they have changed. The crash-on-Cn2 enable bug was fixed, but another version of the bug seems to have popped up. Finally, multilingual versions have been implemented; an English, French, and Spanish version are included in this release. You know the drill: report bugs, comments, and suggestions to me.
