Is there a possibilty to remove unconfirmed transaction from the transactionlist in my wallet? I have really a lot of them and all transactions made when i was at a fork are in front of the actual ones so i have to search every time when i will have a look on the actual transactions.
Yes, that happens sometimes when you send coins that have been mined on fork and later you resync with the main chain. This is one of the problems on my list. I noted it on other coins based on the same old code.
And another Question. Is it normal that i get 90% unconfirmed blocks when i mine solo with GPU? I get several blocks every second, thats a lot to much, but more than 90% disappaers after about 10 confirms. When i mine with -gen option of my wallet i get between 1 or 2 blocks a minute and only 1 block after some hours but they all get their 50 confirms.
It is normal for the current implementation of the wallet. There is a number of different problems that lead to that bad situation. It should be better after I release the updated wallet.
