Dan, I believe Dale is correct. In the past, our KMA importer could allow filenames exactly 64 bytes long. When we went to 4.00, we needed to put an "end-of-field" character in that 64-byte string, so we had to limit the DATA to 63 characters, and the last byte became the "delimiter". I believe that is where we may have a bug. It would only show up if you had 64 bytes in a Title or Name field, or (I forget the field size) the maximum bytes for the Brand (Mfgr) field. These 3 were limited to 1 byte less than before.
It was a judgment call I agree with so we didn't have to redo the KMA Header on every KMA file. That would have required making a backup, and running a Utility program that would convert all your KMA files to a new KMA Header. We felt that was too extreme. Problem is there seems to be a bug in this "truncation" that we didn't find before releasing 4.00.
I've written it up for review tomorrow.
