I am building a properly functioning MOBI. I'm opening the OPF file. The MOBI file looks OK, can be read on Kindle Previewer and Kindle for PC. Only on Kindle Touch it makes problems.
OK, this is weird. I opened the OPF file of the Kindle Users Guide, which I downloaded from Amazon in a sample pack
. Kindle Previewer compited a MOBI file which I copied to the "documents" folder on Kindle. To my surprise, when I tried to open it on Kindle it also crashed. Weird.
