Yes, there is a fixed limit on files/directory entries for the root
directory, this however has nothing to do with the "40 Folder Bug".
The root directory is just a fixed area after the FAT (file allocation table),
of fixed size. The subdirectories are more like files, and can be dynamic
in size. 

The size of the root directory varies with the media and can be changed
when initializing the media, on the atari you can  use the "write
boot block xbios call" for floppies. I don't know what the default sizes
are. This is also a limitation in MS-DOS , since that's what filesystem
format TOS uses.
