Can you share the address or addresses with the bitcoin you're trying to send?
I have amounts in several addresses, so i don't know which were chosen by electrum to be used as an input... I'll retry sending the 0.02, but selecting the option: "view transaction before signing", so i know which inputs it's going to use
Dust is defined as an output below 2730satoshis so one of your outputs may be below that threshold. When you use an input, the input may be bigger than a single output and the remaining is sent as change to another address. The input could have been 0.02002729BTC, 0.02BTC going to destination and 0.00002729BTC going to change address but it's too small. That may be the problem. Try spending the entire input to make only one output or add the change into the fee/reduce the fee by a few satoshis.
Thanks, i didn't even think about this... This is most probably the sollution to my problem...
If the sollution from ranocingo doesn't work, i'll post the addresses, inputs and outputs, as requested...
Thanks guys
