Another wallet bug report, I think...
when sending money I usually use a custom send, where I specify the address I want the BTC to come from, and have the change return to the same address.
I'm also usually adding a small fee for the miners.
Anyways, teh coins send OK, but I am often seeing an error message that says "Error pushing transaction output" or something like that in a read box on the right hand side of the screen.
Like I said, though, it seems that the transactions are going out just fine.
