Trying to process a transaction out of my Multibit wallet, entering the key & the error message 'insufficient money' appears on the screen. I know that I need to add a transaction fee, which I am doing, however the number of Satoshis required increases at every attempt! For instance, the transaction will require 100250 Satoshis, so I will amend the amount being transferred to 100300 to compensate & allow for any fluctuation.
The warning then reappears stating it now requires 100500 Satoshis. This cycle is continuing, I can't find a figure beg enough to get ahead of the curve, without literally throwing my money away! Any help would be appreciated, this has been frustrating me for some time now!
