I tried running a masternode on this coin but it is seriously buggy and was making my Windows pc freeze. The wallet needs work.
The problem might not be in the wallet but inside your mind. I will have Bonzo take a look into it though.
No, there is a problem with the wallet, it locks up often, then starts working again after about 15 seconds. But it is not crashing my computer, and I was able to get my masternodes working, and BTW they are very PROFITABLE!!!!
