Wallet Questions

[uncle_muddy]

I’m working on a little project at the moment, and want to do automated transfers of funds from the wallet. During testing I’m transferring 0.02FTC from the wallet to another address, and I get the below error message

error: {"code":-4,"message":"Error: This transaction requires a transaction fee of at least 0.02 because of its amount, complexity, or use of recently received funds!"}

Question is at what point do funds become not “recently received”? (currently at 8 confirms)

Interestingly when I sent the 0.02FTC from my wallet to the one used by the application I had to pay a transaction fee then as well, because it was over the transaction limit which I also don’t understand.

Thanks for any info/incite you can offer
