Hi JHowell,

Could any of this be helpful in determining if the file is a 'Dual Mobi / Master Mobi'?

ExifTool Version Number         : 11.88
File Type                       : MOBI
File Type Extension             : mobi
MIME Type                       : application/x-mobipocket-ebook
Palm File Type                  : Mobipocket
Compression                     : PalmDOC
Mobi Type                       : Mobipocket Book
KF8 Cover URI                   : kindle:embed:0002

Does the mention of 'KF8 Cover URI' seem interesting in the context of your suggestion?

If it is a 'Dual Mobi / Master Mobi', how do I make it a 'Standard Mobi' so that title shows correctly on my Kindle?


Thanks,

Alan.
