When I try to send BTC from my Electrum wallet address to one of my unused addresses in Electrum, just as a test, it comes up with an error message
(U'message':u'TX rejected, U'code':-22).
I'm using electrum-1.6.2 Install version on my Windows 7 64-bit PC.
I changed the Electrum server and then the transmission worked, so I guess it was an error transmitting data to the server.
Can someone confirm that Error "22" refers to a transmission error to the server? Also, is there a list of error message numbers, so in future I can refer to the list?
