[Resolved]Bitcoin transaction question.

[pekv2]

I've sent a donation of 0.09090909 BTC. Block explorer shows I sent 0.45 with remaining balance of 3.2795. So fired up my bitcoin wallet machine to check the balance, and it shows a balance of 3.64859091 BTC. Also blockexplorer shows I've sent a total of 0.35909091 to *link removed* along with that donation of 0.09090909 to *link removed*

Why did bitcoin client send off 0.35909091 to *link removed*

I am totally lost of words atm.

Here is my wallet address if you wanna check it out *link removed*

Edit:
Removed address link's.

When you send a transaction, the client send some money to a hidden address in your wallet

So, is that 0.35909091 hidden from the total balance showing on my client? Also it came back to my wallet? I don't really comprehend.

Thanks.

It is counted in the balance, the address is just not shown

This behaviour is used because you can't use only a part of a transaction
So the client took the 0.45 transaction you received about 2 weeks ago (a9e4...), sent the donation to your 18neW..., and sent the remaining bitcoins to one of your wallet hidden addresses
This way, you still have the money you own, but you don't see a useless 0.35909091 transaction in your wallet

I hope it's clearer
