Thank you very much! I'm actually trying your wallet, looks good
But, i sent worth of 2 ltc of dime without the error "transaction too large", and this is good but still unconfirmed for 25min

(the amount is still here in my wallet if i reload the old wallet, it is not lost).
I send a little amount too, who are well confirmed. It seem like the new feature of larger transaction amount is not working fine ?!
Also @lulupon i'm around 3% of rejected now, well better than 8% ! my ping was ~1000ms, now more like 200ms. As i understood, a p2pool made random ping ? There is a risk that my ping go higher again ?
Answer 1 : If you are mining in P2pool, there is a plenty of (unspent)transaction in your wallet.
One simple solution is merging transaction, send dimecoin to your self address in your wallet frequently.

Answer 2 : My humble server is stored in IDC. But, I have no money to upgrade my server

In such cases, please don't think that I'm rude and please do understand.
