Folks, from what I've been able to glean from a re-read of these forums - it appears that those of us with Kindle FW v3.1 are having the same sort of problems i.e. collections appearing to be all good on the KCM, but not on the Kindle itself.
Adrian, I hope hope hope you are out there in cyberspace working on the next iteration of KCM... Pleeeeeeeeeze
Just want you to know how much we appreciate you developing this product
Lots of eager beta testers here awaiting the next update
cheers,
HBH
