@xeroc: thanks but unfortunately that doesn't help much. I am using the DNS client to retrieve the keys as these are DNS balances.
Unless the client produces a lot of keys that do not 'hold' any DNS, my keys seem not to be part of the allocation as mentioned in the OP.
So either I missed something or there seems to be a problem.
I will export all the keys or increase the scroll buffer
to check every single key (by script) tonight.
Just was wondering that there are so many keys that are not in the genesis file.
If anyone knows an easy way to check if/how much a public key 'holds' please let me know.
