I do not understand much either. I launch the wallet, it shows a balance of 0.0 MAP. and the bottom is written synchronization 1/1 and the lower right corner in the corner of the white arrows. on another computer I started my wallet and there is not this synchronization and it seems like the wallet is synchronized, but I / O columns / information about the purse they are all not working, black and not active. Nodes do not help.
