Doors CS RC3 brings a new set of bugfixes and tweaks to the ever-improving Doors CS shell, one step closer to completion. Debouncing has been added to file renaming and folder creation, a scrollbar misalignment was fixed in FileOpen and FileSaveAs, and the alpha indicator was fixed from a previous change. In addition, interrupt issues with Ion-derivative routines were repaired, FileSaveAs no longer accepts blank filenames, and most importantly, a subtle misalignment bug was fixed that prevents variable-size AP files from crashing Doors CS.
