I just got my first GUN Wallet 1.3 (desktop) a few weeks ago.  All this crypto stuff is new to me.  I upgraded to GUN 1.4 on my desktop with no problem.  I copied my .guncoin to my laptop and installed another GUN Wallet 1.4 there with no problems.  So... will having two GUN Wallets potentially running at the same time like this cause any problems?
