For some disks (100MB Zip disks), the Scan function won't scan the disk
and add a new catalog. No error messages are given. Existing Catfish
and doing another scan does not affect the results. Windows Explorer
(or whatever it is) can see the files and directories just fine. Catfish
does detect the volume name correctly.

There is a known issue with long catalog names, but I don't think this is
the case here. Also, there may be differences in file system: VFAT vs. NTFS (what
does ZIP use?). The trouble seems to be caused by XP supported for old 16-bit
apps (yes that's right, CatFish still runs on Win 3.1 and up).
I'm not sure how to fix this.
